Name: Class Period: Week 18 DCA Study Guide Please remember this is a STUDY GUIDE, you should read/study your journals, graded papers, review power points on the class website, read/study information in the online textbooks, and request tutoring if necessary. The DCA will be on _Wednesday, January 16th. Complete The Following ChartsSTRUCTURE FUNCTION BODY SYS or Organ Nucleus Control the activities of the cell Brain Vacuole Store water, food, some waste Urinary bladder, large intestine Lysosome Breakdown molecules, waste Liver, digestive system Cell Wall Rigid, give support and shape Skeletal System Mitochondria Produces energy for the cell Digestive system, adrenaline Ribosomes Synthesizes proteins Muscles Endoplasmic Reticulum Assembles molecules and transport them across the cell Circulatory System (blood vessels) Chloroplast Transform radiant energy into chemical energy (glucose) Digestive system Cytoplasm Jellylike substance keeps cell organelles in place Connective tissue (tendons, ligaments, mesentery) Cell Membrane Surrounds the cells controls what enters and leaves the cell Alveoli, Digestive System TROPISM STIMULI Skin, Integumentary System RESPONSE Chromotropism Blue light Plant stem bends toward light Hydrotropism Moisture Roots grow toward water Geotropism / Gravitropism Gravity Roots grow down, stems up Phototropism Dim/Bright Light Plants bend toward light Thigmotropism Fence post, tree, side of a house Plant “climbs” up object Themrotropism Exposure to fire Plant seed germinates Complete the following questions. 1. What are the 3 main parts of The Cell Theory? 1) all living things are made of cells 2) all cells come form pre-existing cells, and 3) the cell is the basic complete unit of living things. 2. Compare photosynthesis and cellular respiration – how are they alike? How are they different? They are chemical reactions that take place in cells and involve the transformation of energy. Although they use the same compounds the reactions are opposite from one another. Photosynthesis takes place in the cells of autotrophs, cellular respiration occurs in the cells of autotrophs and and heterotrophs. 3. Write out the chemical equation for Photosynthesis – label the products, reactants, describe the energy transformation that takes place, name the organelle that it takes place in: 6CO2 + 6H2O Reactants >>>> C6H12O6 + 6O2 Sunlight Products absorbed Radiant energy from the sun is absorbed by the chlorophyll in chloroplasts of plant cells and transformed into chemical energy called glucose (sugar). 4. Write out the chemical equation for Cellular Respiration – label the products, reactants, describe the energy transformation that takes place, name the organelle that it takes place in: C6H12O6 + 6O2 >>>> 6CO2 Reactants ATP (thermal energy) Products + 6H2O released Chemical energy in the form of glucose (sugar) is transformed into ATP (thermal energy) in the mitochondrion of cells 5. Describe trait – include a definition, an example, the name of the molecule that codes for a trait and where the molecule is located in a cell. Traits are characteristics of organisms such as hair color, skin tone etc. Traits can be inherited or acquired. Inherited traits are passed down to offspring form parents and are coded for by genes. Genes are sections fo DNA that contain information about an organism. DNA makes up the chromosomes (chromatin) which is found in the nucleus of eukaryotic cells. Genetic material of prokaryotic cells is found in the cytoplasm. THIS IS ONLY A STUDY GUIDE AND COVERS ONLY THE BASIC CONCEPTS, TO SUCCESSFULLY COMPLETE THE 18 wk DCA YOU MUST BE ABLE TO APPLY THE CONCEPTS TO “REAL WORLD” EXAMPLES AND SITUATIONS.
