Name: Class Period: Week 18 CCA Study Guide Remember this worksheet is meant only to be a guide to help you prepare for the up coming test. You should also access the online textbook, study your journal, and cell diagrams. TROPISM STIMULI RESPONSE Moisture Geotropism / Gravitropism Phototropism Fence post, tree, side of a house ORGANELLE Many Small Vacuoles One Large Vacuole Cell Wall Cell Membrane Chromosomes / DNA Nucleus Ribosomes Mitochondria Chloroplast / Chlorophyll Endoplasmic Reticulum PLANT CELL 1. Why do we refer to the nucleus as the “brain” of the cell? 2. Which organelle is called the cell’s powerhouse AND why? 3. What are the 3 main parts of The Cell Theory? ANIMAL CELL 4. Describe the process of photosynthesis – include the organelle where it takes place, the reactants (what it needs), the products (what it produces), and the energy transformation that takes place. 5. What could a person observe at the cell level and organism level that would indicate that a plant was suffering from dehydration? 6. What is Turgor Pressure and why is it important? 7. List the levels of organization in the body from smallest to largest. Complete the Chart Below STRUCTURE FUNCTION Nucleus Lysosome BODY SYS or Organ Brain, Nervous System Store water, food, some waste Breakdown molecules, waste Skeletal System Mitochondria Synthesizes proteins Assembles molecules and transport them across the cell Chloroplast Jellylike substance keeps cell organelles in place Cell Membrane Connective tissue (tendons, ligaments, mesentery) Alveoli, Digestive System Skin, Integumentary System 8. How might your body respond if you had an infection such as strep throat? 9. When your body is preparing to “fight or flight” what changes might you experience? 10. Indicate if the following are examples of Internal (I) or External (E) stimuli. feeling hungry feeling heat from a flame stepping on a rock low blood sugar levels low blood oxygen levels fire alarm you salivate when you smell cookies cooking tickle in your throat lack of food lack of water 11. Indicate if the following are examples of stimuli (S) or a response (R). sweating increased blood pressure increase insulin levels plant wilting 12. shivering feeling thirsty goose bumps gravity What force do your veins have to overcome to push your blood back to your heart?
