Examples Halophiles, thermophiles E coli Staphycoccus Amoeba, protozoa, algae, slime molds Yeast, mushrooms, ALL molds (except slime and water) Trees, ferns mosses, corm wheat You, sponges, dogs, jellyfish Content Domain 2: Cellular Basis of Life 1. List the 3 parts of the cell theory: 1-basic unit of life 2-all living things are made of at least one cell 3-all cells come from pre-existing cells 2. List the characteristics of living things: a. Made of cells b. Require food for chemical energy to carry out life processes c. Respond to stimuli in their environment d. Produce offspring e. grow and develop f. Maintain homeostasis; a balance of internal conditions g. Have and pass on a genetic (DNA) code 3. A unicellularorganism has to perform all metabolic activities within one cell. 4. A multicellular organism has specialized cells that perform certain jobs. 5. In multicellular organisms, a group of related cells makes up tissue, which makes up organ, which are grouped into organ system which work together to make up the organism. 6. A prokaryotic cell does NOT contain a nucleus or membrane-bound organelles. 7. A EUKARYORIC cell does have a nucleus and other organelles. 8. PASSIVE transport does not require energy. There are 3 examples: a. DIFFUSION- movement of materials from high to low concentration. b. OSMOSIS- movement of water from high to low concentration. c. FACILTAED DIFFUSION- movement of materials from high to low, with the help of a transport protein. 9. ACTIVE transport does require energy input from the cell because materials are moving against the concentration gradient, from LOW to HIGH. 10. Large particles may be engulfed into the cell by ENDOCYTOSIS(phagocytosis); while they are removed from the cell by EXOCYTOSIS. Both of these require energy. 11. If a cell is placed in a HYPERTONIC solution, water will leave the cell, causing it to SHRINK. Remember, water also goes from HIGH to LOW. 12. If a cell is placed in a HYPOTONIC solution, water will enter the cell, causing it to EXPAND OR BURST. 13. If a cell is placed in an ISOTONIC solution, there will be no net movement of water because dynamic equilibrium has already been reached. Label the following solutions as hypotonic, hypertonic, or isotonic. Use arrows to indicate the direction water will move. 5% NaCl 15% other 80% water 10% NaCl 15% other 75% water hypertonic Match the organelle with its function. 14. _E_plasma (cell) membrane 15. _J__chloroplast 16. _F__nucleus 17. _A__nuclear membrane 18. _C_cytoplasm 19. _B__cell wall 20. _I__Golgi body 21. _K__endoplasmic reticulum 22. _D__ribosome 23. _L__chromatin/chromosome 24. _H___vacuole 25. _G__mitochondria a.

MATTER is anything that takes up space and has mass. The 3 states are GAS, LIQUID and SOLID. 2. The ATOM is the building block of all matter. 3. An ELEMENT is a substance made up of all the same kind of atoms. The most common ones found in living things are carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus. 4. hydrogen bonds: weak attractions between polar molecules. Ex- holds water molecules to other water molecules; holds nitrogenous bases together in DNA molecule 5. A chemical REACTION is when chemical bonds are broken and new bonds form. 6. An ORGANIC compound always contains carbon and hydrogen. 7. An INORGANIC compound does not contain C & H and comes from nonliving things. 8. The most important inorganic compound for living things is WATER It is polar (the hydrogen side is positive while the oxygen side is negative). It is a great SOLVENT (it can dissolve most things), necessary for most chemical reactions in living things. 9. The Ph scale, from 0 to 14, is a measure of how acidic or basic something is. Neutral is7 Acids are less than 7. Acids release hydrogen ions (H+). Bases are more than 7. Bases release hydroxide ions (OH-). Stronger acids and bases are FURTHER from 7, while weaker acids and bases are CLOSER to 7. 10. The four basic types of organic compounds found in living things are PROTEINS, LIPID, CARBOHYDRATES & NUCLEIC ACIDS 11. Carbohydrates contain these 3 elements: C, H, & O. Carbs provide a major source of energy. Monosaccharide example: GLUCOSE_ polysacchararide example: STARCH and cellulose 12. Three types of lipids are WAXES, OILS AND TRIGLYGERIDES The building blocks of TRIGLYCERIDES are 1 GLCEROL and 3 FATTY ACIDS Uses in the body: ALL CELL MEMBRANES, SOME HORMONES, STORED ENERGY AND INSULATION 13. Proteins contain these elements: C, H, O, N The building blocks are AMINO ACIDS. They are used for growth and repair. A special type of protein that LOWERS THE ENERGY OF ACTIVATION in a chemical reaction is called an enzyme. 14. Nucleic acids contain an organism’s GENETIC CODE The building blocks are NUCLEOTIDES. Ex: DNA & RNA 15. When cells break down glucose to make energy, they are carrying out CELLULAR RESPIRATION Plants get this food by performing PHOTOSYNTHESIS 16. Write the balanced chemical equation for cellular respiration: Circle the reactants, underline the products. C6H1206 + 6O2 H2O + 6CO2 17. Write the balanced chemical equation for photosynthesis: Circle the reactants, underline the products. H2O + 6CO2 C6H1206 + 6O2 18. The molecule that cells use to carry out cellular activities is called ATP Energy is released when one P, PHOSPHATEis removed, formingADP 19. What is the ultimate source of energy for all living things? SUNLIGHT 20. What is the difference between aerobic and anaerobic respiration? OXYGEN 21. What are the 2 types of anaerobic respiration?_LACTIC ACID AND ETHANOL How many net ATPs are produced in each? 2 ATP How many net ATPs are produced in aerobic respiration? 36 ATP DNA Replication, Transcription, and Translation 22. What 3 things make up a nucleotide? N BASE, PHOSPHATE GROUP & SUGAR 23. How do the nitrogenous bases pair up? HYDROGEN BONDING 24. What would the complementary strand of DNA look like for: A T T C G C A T G? TAAGCTTAC 25. Name 3 ways that DNA and RNA differ DOUBLE V SINGLE STRANDED, THYMINE INSTEAD OF URACIL N BASE, BIG V SMALL, ONLY IN THE NUCLEUS V ALL OVER THE CELL 26. What are the 3 types of RNA and what do they do? TRNA CARRIES MINO ACIDS TO TO THE RIBOSOME, MRNA COPIES THE DNA AND CARRIES THE MESSAGE TO THE RIBOSOME TO MAKE THE PROTEIN RRNA MAKES UP THE RIBOSOMES 27. What is it called when DNA is used to make mRNA? TRANSCRIPTION 28. Transcribe the following A T T C G C A T G UAAGCGUAC 29. Three bases in a row make up a CODON. This matches to the ANTICODON found on the TRNA. The tRNA carries the appropriate AMINO ACID to build a protein. This occurs at the RIBOSOME. This final process is called protein synthesis, or TRANSLATION. 30. What shape does a DNA molecule have? DOUBLE HELIX Content Domain IV: Genetics and Patterns of Change 1. The 2 main stages of the cell cycle are M PHASE (MITOSIS) AND INTERPHASE 2. Interphase is the longest phase. What 3 things happen during this phase? a. G1 GROWTH AND WORK b. S DNA SYNTHESIS c. G2 FINAL PREP FOR MITOSIS 3. Mitosis is the division of the NUCLEUS in EUKARYOTIC cells. 4. Cytokinesis is the division of the CYTOPLASM. 5. The two resulting cells are IDENTICAL and are called DAUGHTER cells. 6. The four phases of mitosis are (include a description of each): a. PROPHASE _______________________________________________________ b. METAPHASE: _______________________________________________________ c. ANAPHASE: _______________________________________________________ d. TELOPHASE_: _______________________________________________________ Label the following diagrams and put them in order. 2 METAPHASE 3 ANAPHASE 4 TELOPHASE 1 PROPHASE INTERPHASE(not a part of mitosis) 7. The difference between animal cell division and plant cell division is the formation of a cell PLATE in PLANT cells 8. Cell division is necessary in order for a cell to REPLACE ITSELF AND PREVENT DNA OVERLOAD 9. Mitosis makes TWO cells, which means there are 2 of each chromosome (pairs). In humans, these cells have 46 chromosomes. Since the 2 chromosomes in the pair are similar, they are referred to as HOMOLOGOUS. 10. Meiosis is how SEXcells are formed (also called GAMETES). They have HALF the number of chromosomes and are therefore referred to as HAPLOIDcells. 11. In meiosis, 4 cells are formed, all of which are NONIDENTICAL. In egg production, only ONE egg forms, along with 3 POLAR BODIES It makes FOUR sperm. Genetics 12. Genetics is the study of HEREDITY. The father of genetics was GREGOR MENDEL, who did his research on PEA plants. 13. A characteristic a person receives from his/her parent is a TRAIT. The instructions for them are carried on DNA, which are found on CHROMOSOMES. 14. A person gets one gene for each trait from each parent. The alternative versions of genes are known as ALLELES If the two alleles are identical, the pair is HOMOZYGOUS, if the pair is different, it is HETEROZYGOUS, or hybrid. The combination of alleles is called the GENOTYPE, while the physical appearance is the PHENOTYPE 15. The allele that shows up is DOMINANT, while the one that is hidden is RECESSIVE. 16. Mendel’s work is summarized in 3 laws: a. Law of Dominance: In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. b. Law of Segregation: members of a pair of homologous chromosomes separate during the formation of gametes and are distributed to different gametes so that every gamete receives only one member of the pair c. Law of Independent Assortment: the alleles for a trait separate when gametes are formed 17. A genetic cross involving only one trait is a MONOHYBRID trait. If it involves 2 traits, it is a DIHYBRID trait. The cross is done on a PUNNETT square. 18. Black fur is dominant to white fur in rabbits. If a heterozygous rabbit is crossed with a white rabbit, what will the genotypic and phenotypic ratios of the offspring be? Bb x bb_ __B__ __b__ Genotypic ratio: 2/4 Bb 2/4 bb Phenotypic ratio: 2/4 black 2/4 white __b__ Bb bb __b__ Bb bb 19. The sex chromosomes in males are X Y, while females have XX. 20. Some traits are carried only on the sex chromosomes. These are called SEX-LINKED traits. Usually, they are on the X chromosome, so are more common in males since males only have ONE X chromosomes. 21. During meiosis, homologous chromosomes may CROSS over, resulting in a new combination of genes. 22. Changes in the genetic code of an organism result from MUTATION, which may be spontaneous or caused by a MUTAGEN. 23. Sometimes during meiosis, homologous pairs do not separate, so the resulting sperm or eggs will have either one extra or one missing chromosome. This is called NONDISJUNCTION and can lead to genetic disoders called trisomy or monosomy. An example of a trisomy of the 21st chromosome is DOWN’S SYNDROME 24. Genetic ENGINEERING has lead to many advances in medicine and agriculture. Bacteria have been produced that can make insulin, thanks to TRANSGENIC DNA. 25. When a species changes over time, it is referred to as EVOLUTION. This occurs due to NATURAL SELECTION. This theory was proposed by CHARLES DARWIN. 26. According to natural selection, organisms that are BEST suited to their environment will SURVIVE and REPRODUCE, therefore passing on their traits. 27. Evolution that involves small changes in a species is called MICROEVOLUTION. 28. Evolution that occurs slowly over where big changes occur is called MACROEVOLUTION. Content Domain 5: Viruses, Monerans, Protists, and Fungi Viruses 1. Viruses are [living, nonliving]. They are composed of an outer CAPSID OR PROTEIN SHELL, with DNA OR RNA (GENOME) inside. They must replicate IN A HOST CELL (where). 2. When a virus injects its DNA into the host cell, it hijacks the host, forcing it to MAKE COPIES of viral DNA. Once the viral proteins are assembled, the cell BURSTS, releasing the viruses. This is referred to as the LYTIC cycle. 3. If the viral DNA is not immediately copied, it becomes integrated within the HOST’S DNA When the host cell divides, the daughter cells produced will also contain copies of the VIRUS DNA The virus may be DORMANT/LATENT for several years in this state, but it is being spread. This is called the LYSOGENIC cycle. After time the lytic cycle will take over CAUSING ACUTE DISEASE AGAIN. 4. Some common diseases caused by viruses are HERPES, CHICKEN POX, COLDS AND FLU. 5. Viruses do not respond to ANTIBIOTICS. The body produces ANTIBODIES to help fight viruses. Animals can receive immunity from viruses through VACCINES, which is when the animal is injected with dead or weakened viruses so that ANTIBODIES will be produced against it. Bacteria 6. Bacteria belong to the Kingdoms archeabacteria and EUBACTERIA. They are UNI-celled organisms [with, without] a nucleus. Therefore they are referred to as PROKARYOTES. 7. Most bacteria are HETEROTROPHS because they must get food from an outside source. However, blue-green bacteria are AUTOTROPHS who do photosynthesis. Some perform CHEMOSYNTHESIS, getting food from chemical compounds. 8. The three shapes of bacteria are COCCI(which is A SPHERE), BACILLI(which is ROD SHAPED), and SPIRELLA, (which is A SPIRAL). 9. The circular DNA of bacteria is called a CHROMOSOME. Some bacteria also have a tail, called a FLAGELLA. Some bacteria form ENDOSPORES, in which the DNA is protected in a coating until conditions are favorable. The process whereby bacteria MOST reproduce is referred to as BINARY FISSION They cannot do mitosis, since there is no NUCLEUS. 10. In what ways are bacteria beneficial to us? MAKE FOOD, MEDICINE, HELP DIGESTION, PROTECT FROM BAD BACTERIA 11. What are some foods produced with bacteria?YOGURT, COTTAGE CHEESE, KIMCHI, PICKLES , SAURKRAUT 12. Some common diseases caused by bacteria are STREP THROAT, PNEUMONIA, SYPHILLIS AND CAVITIES 13. Some bacteria cause disease by releasing TOXINS, while others cause disease by breaking down tissues for FOOD. Bacterial diseases can be transmitted by SURFACES, EXCHANGE OF FLUIDS, DIRECT CONTACT, or VECTORS (like ticks, fleas, lice, raccoons, etc.). To fight bacterial infections, ANTIBIOTICS may be taken. 14. Some ways to prevent bacterial infection are STERILIZATION, PASTUERIZATION, GOOD HYGENE AND HAND WASHING. Protists 15. Kingdom Protista is composed of mostly UNIcelled organisms that all have a MEMBRANE-bound NUCLEUS. Thus, they are referred to as EUKARYOTES. 16. Plant-like protists are known as ALGAE; animal-like protists are referred to as PROTOZOA, while fungus-like protists are just fungus-like protists! 17. Protozoa are classified based on their method of MOVEMENT. 18. Algae contain CHLOROPHYLL in order to do photosynthesis. They must live in a WATER environment. They are generally classified based on the color PIGMENTS they contain. 19. How are protists beneficial? FOOD, CONSTRUCTION, CLEANING PRODUCTS, OXYGEN PRODUCTION 20. What are some diseases caused by protists? MALARIA, CHAGAS DISEASE, DYSENTARY 21. What is an algal bloom? RAPID GROWTH OF ALGEA DUE TO INCREASE IN NITROGEN (USALLY ANIMAL WASTE) IN WATER 22. What causes red tides? AN ALGAL BLOOM OF A RED ALGAE Fungi 23. Fungi are usually MULTI-celled organisms that must OBTAIN FOOD to get energy. Unlike plants, they DO NOT perform PHOTOSYNTHESIS. 24. Fungi are made of filaments called HYPHAE, which intertwine into a tangled mass known as a MYCELLIUM. Their cell walls are composed of CHITIN. 25. Fungi reproduce both SEXUALLY AND ASEXUALLY They are classified based on the way they form SPORES. 26. How are fungi beneficial? FOOD(MAKE AND ARE), MEDICINE, DECOMPOSERS 27. What are some foods produced with fungi? CHEESES, BREAD(YEAST), SOY SAUCE 28. What are some diseased caused by fungi? ATHLETES FOOT, THRUSH, RINGWORM What are some negative effects of fungi? GROW ON ANYTHING AND “DECOMPOSE IT” Who am I? PARAMECIUM AND AMOEBA Content Domain 6: Ecology and the Environment 1. The thin layer of land, air, and water where life on Earth exists is the BIOSHPERE. 2. Ecology is the study of the interactions between ORGANISMS and their ENVIRONMENT. 3. A group of the same species of organisms living in an area is a POPULATION. 4. All of the species in an area is a COMMUNITY 5. Different species of organisms in an area, plus the nonliving parts of the environment make up the ECOSYSTEM_. 6. Environmental factors that are living are referred to as BIOTIC, while those that are nonliving are known as ABIOTIC. Plants, animals, and bacteria are examples of biotic factors. Five examples of abiotic factors are TEMPERATURE, CLIMATE, SPACE, WATER AND AIR. 7. The place where an organism lives is its HABITAT, while it’s “job” or “way of life” is called its NICHE. 8. The ultimate source of energy in an ecosystem is the SUN, but only 10% of this energy is transferred to the next TROPHIC level. 9. Organisms that make their own food are called AUTOTROPHS OR PRODUCERS They are found at the BOTTOMof the energy PYRAMID. 10. The path of energy from producer to consumer is a FOOD CHAIN Make one containing at least four organisms. GRASS_GRASSHOPPERSONGBIRDHAWK 11. Many interconnected food chains make up a FOOD WEB 12. T or F. Energy is recycled in an ecosystem. 13. T or F. Matter is recycled in an ecosystem. 14. Water Cycle: Rain, snow, and sleet are examples of PRECIPITATION. When liquid water changes into the gaseous state, it is called EVAPORATION. When water evaporates from leaves into the atmosphere, it is called TRANSPIRATION. When water changes from a gaseous state to a liquid state, it is called CONDENSATION. 15. Nitrogen Cycle: BACTERIA are found in the root nodules of special plants called LEGUMES; they convert nitrogen gas into a usable form for the plants. Animals get this nitrogen when they EAT PLANTS AND OTHER FOOD. When organisms die, nitrogen is returned to the soil. 16. Carbon Cycle: Carbon enters the atmosphere when FOSSIL FUELS OR ANY ORGANIC MATERIALS are burned, when organisms do cell RESPIRATION, and during volcanic eruptions. Carbon leaves the atmosphere (CO2-abiotic) and enters the biotic parts when plants perform PHOTOSYNTHESIS. CO2 is also produced when decomposers break down dead organisms. 17. Phosphorus Cycle: Plants get phosphorus from the soil and rocks. Animals get it when they EAT. It is returned to the soil when plants and animals DECOMPOSE 18. When communities change over time, it is called ecological SUCCESSION. There are 2 types. If NO LIFE existed there before, it is PRIMARY SUCCESSION The first organisms to colonize such an area are pioneer species, such as LICHEN. What types of organisms are next? AFTER SOIL IS FORMED, PLANTS LIKE MOSSES 19. When there used to be life, but a disaster occurs, killing everything, SECONDARY succession occurs. It is faster because SOIL is already present. This type usually begins with things like GRASSES AND OTHER SMALL PLANTS. 20. A community that is relatively stable and unlikely to change is called a CLIMAX community. 21. If the number of births equals the number of deaths in a community, ZERO POPULATION GROWTH is the result. 22. If the population grows exponentially because there are no LIMITING factors, the growth curve looks like the letter J. The population size will rapidly exceed the AVAILABLE FOOD AND SPACE, CALLED CARRYING CAPACITY and will likely crash. 23. If the population levels off (stabilizes) at the CARRYING CAPACITY due to LIMITING factors, the curve is called logistic, and is shaped like the letter S 24. Some examples of limiting factors are SPACE, FOOD AVAILABLE MATES, DISEASE 25. A large region that has a certain climate and characteristic animals and plants is called a BIOME. The climate is based on amount of PRECIPITATION and TEMPERATURE. Biome Tropical rainforest Climate WET WARM Animals MANY -HIGH DIVERSITY Savanna WARM SEASONAL PRECIP GRAZING & BURROWING Desert HOT DRY REPTILES MANY NOCTURNAL Temperate grassland SEASONAL TEMPS & PRECIP SEASONAL TEMPS & MODERATE PRECIP COOL TO COLD MOD PRECIP GRAZING & BURROWING WIDE VARIETY Temperate forest Taiga Tundra COLD & DRY PERMAFROST WIDE VARIETY OF COLD TOLERANT SP FEW IN VARIETY MANY IN # Plants MANY BROAD LEAF PLANTS & TREES GRASSES & SHRUBS SOME TREES SPINY LEAVED W/ WAXY COVERINGS GRASSES & SHRUBS MANY DECIDUOUS TREES CONIFEROUS TREES SEDGES. MOSSES SMALL PLANTS 26. Aquatic environments: examples of standing FRESH water: ARE LAKES AND PONDS, examples of moving water:RIVERS AND STREAMS There is freshwater and SALT 27. The photic zones of lakes and the ocean have LIGHT, while WATER(MARINE). An ESTUARY is a combination of the two.the aphotic zone can only support organisms that can live in the DARK_. 28. What are some ways humans have caused the extinction of species? HABITAT DESTRUCTION, POLLUTION, OVERHUNTING/HARVESTING 29. A harmful product, or waste product in the environment is a POLLUTANT. Much air pollution is caused from burning of FOSSIL FULES Examples of air pollutants are CO2, CO, NOx, SOx, SMOG, OZONE, CFCs. A combination of smoke, gases is called SMOG. If air pollutants SOx and NOx (sulfur oxides and nitrous oxides) combine with water vapor, it produces ACID RAIN (PRECIPITATION) 30. The greenhouse effect is vital on our planet to MAINTAIN temperature. If too much carbon dioxide, a greenhouse gas, is present in the atmosphere, it leads to the INCREASE OF THE GREENHOUSE effect. This is thought to contribute to GLOBAL WARMING 31. What are some things that may cause water pollution? INDUSTRY, ANIMAL WASTE, MINING, IMPROPER DUMPING (THINK Simpson’s movie) 32. What are two alternate sources of energy for electricity, instead of burning fossil fuels? SOLAR power & WIND power 33. All plants are [unicellular, multicellular] and are [eukaryotes, prokaryotes]. 34. Plant cells contain 2 things not found in animal cells: CELL WALL & CHLOROPLASTS 35. The cell walls are made of CELLULOSE which is a type of CARBOHYDRATE. 36. Some small plants transport water and food only by diffusion. These are ________________ plants. Larger, more complex ________________ plants have conductive tissue for this job. 37. Bryophytes (2 examples: mosses & hornworts) are nonvascular plants that reproduce by producing spores. -found in WET environments. 38. Plant life cycles are referred to as “alternation of generations”, cycling between haploid 39. (1 N, gametophyte) and diploid (2 N, sporophyte) generations. 40. Alternation of generations: the haploid gametophyte generation produces GAMETES (eggs & sperm) by mitosis. They come together to form a ZYGOTE, which is the sporophyte. The sporophyte then produces SPORES by meiosis. They develop into the gametophyte. 41. The two types of vascular tissue are XYLEM (which transports WATER up from the roots to the rest of the plant) and PHLOEM (which transports GLUCOSE from the leaves to the rest of the plant). 42. The seed of a plant contains the EMBRYO and a food supply (endosperm) surrounded by the SEED COAT. 43. Seed-producing plants are divided into 2 groups: GYMNOSPERM (naked seeds, often in cones) and ANGIOSPERM (flowering plants). Examples of gymnosperms are PINES, CEDARS, SEQUOIA & CONIFERS Examples of angiosperms are CORN, GRASS, OAKS, ROSES, AND APPLE TREES 44. In flowers, the seeds are protected within a FRUIT (an enlarged ovary). They are further divided into 2 groups: monocots (one cotyledon, ex-GRASS & corn) and dicots (2 cotyledons, ex-POISON IVY & roses). 45. The three main organs of a plant are the LEAVES, ROOTS & STEMS 46. Three jobs of roots:ABSORB WATER AND NUTRIENTS & ANCHOR THE PLANT. Two kinds of roots: TAP & FIBROUS. 47. Two jobs of stems: SUPPORT & TRANSPORT. 48. Main job of leaves: PHOTOSYNTHESIS 49. What can carry their pollen? WIND, WATER & ANIMALS 50. Under the right conditions, seeds will sprout, or GERMINATE. 51. What are some ways that humans use plants? FOOD, PRODUCE OXYGEN 52. Label the parts of the flower. Word Bank pistil petal stamen stigma ovary ovule filament style anther sepal 20. Animals with a backbone are VERTABRATES; those without are INVERTABRATES 21. Comparative Invertebrate Survey…this should look like a table you have already done! 22. All vertebrates have BILATERAL symmetry, a [true coelom, pseudocoelom, or no coelom] and an [endoskeleton, exoskeleton].
