Succession The series of changes that occurs in an ecosystem with the passing of time The process of mixing decaying leaves, manure and other nutritive matter to improve and fertilize soil Composting Remember Worm Bins What is this equation? Sunlight 6CO2 + 6H2O C6H12O6 + 6 H20 Chlorophyll Photosynthesis The process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food The process by which plants release water vapor into the air through stomata Transpiration The growth of all or part of the organism in response to an external stimulus, such as light Tropism What makes this leaf green? Chlorophyll A green pigment that captures light energy for photosynthesis What is it called when egg and sperm meet? Egg Sperm Fertilization What are these pictures showing? Pest A label applied to an organism when it is in competition with humans for some resource A species that is in danger of extinction throughout all or significant portion of its range Endangered Species The land area from which surface runoff drains into a stream, channel, lake, reservoir or other body of water; also called drainage basin Watershed A naturally occurring raw material or form of energy that will be replenished through natural ecological cycles or sound management practices Renewable Resource • Wind, Water, Sun and Trees Oil, Gas Copper, Gold etc. are examples of what? Nonrenewable Resources Substances that once used, cannot be replaced in this geological age What type of cell is this? Animal Cell Remember animal cells are round and have a lysosomes These 3 statements make up what? • All living things are composed of cells • Cells are the basic function and structure of life • All cells come from other cells The Cell Theory A and B represent what type of cells? B A A is a eukaryotic cell Has a nucleus B is a prokaryotic cell Has NO nucleus What does the picture represent? Mitosis The sequential differentiation and segregation of replicated chromosomes in a cell’s nucleus that preceded complete cell division The movement of substances across a cell membrane without the use of energy by the cell Passive Transport An “If” “Then” statement is used in what? A Hypothesis The apple is green is a _____________ description a. Qualitative b. Quantitative c. Data A. Qualitative The physical characteristics of an object The division of organisms into groups, or classes, based on specific characteristics Classification Remember: Kingdom Phylum Class Order Family Genus Species State the question collect information Research information State a hypothesis Test hypothesis Observe testing Record data State a conclusion of your hypothesis The Scientific Method Homo sapien What is the Genus and what is the species? •Genus: Homo •Species: sapien What does DNA Stand for? Spell it right! Deoxyribonucleic Acid Give me the genotype for the following phenotype Square body is dominant to round body Genotypes to square body is dominant to round body: SS: Square Ss: Square ss: Round Tell me if the following genotypes were heterozygous (He) and homozygous (Ho) Dd JJ mm ff KK Ll •Dd: He •JJ: Ho •mm: Ho ff: Ho KK: Ho Ll: He What are the parents? ? ? ? BB Bb ? Bb bb B b B BB Bb b Bb bb How are II 8 and III 3 related? Person II 8 is person III 3 aunt or person III 3 is person II 8 niece Pollutants discharged from a single identifiable location (ex pipes, ditches, channels, sewers) Point Source Pollution Relating to living in actively moving water Lotic A community of living organisms of a single major ecological region Biome What does this sign symbolize? Recycling Collecting and reprocessing a resource into products to make new products Name the 3 greatest Life Science Teachers EVER! Greatest Science Teachers EVER In NO Specific Order Zajicek Paige Broderick A characteristic that improves an individual’s ability to survive and reproduce in a particular environment Adaptation Monkeys Adapted Tail for swinging and grabbing bananas Herbivores eat what? Plant eaters Elephants are herbivores The process by which individuals that are better adapted to their environment survive and reproduce more successfully then less well adapted individuals do; a theory to explain the mechanism of evolution Natural Selection • Zebras, over the years have survived because of their strips which are a naturally selected trait An organism that can make its own food by using energy from its surrounding Producer Plants are producers What is this diagram called? Food Web Remember this shows all the living things (plant & animal) interacting in an ecosystem
