Name: __________________________________________ Class Period: ________________ Cell Study Guide 1. How does a cell’s mitochondria help the cell carry on life-sustaining functions? 2. What cell structures are necessary to ALL cells? 3. Tanya observes an unknown one-celled organism that swims around and has a chloroplast. What does this tell her about this cell? 4. What jobs does the cell membrane perform? 5. Which parts help a cell to get energy? 6. What is necessary for active transport? 7. When would active transport be necessary for a cell to take in nutrients? 8. Why do cells need nutrients? 9. There is a lower concentration of water outside a cell than inside the cell. What type of transport will occur? 10. Tariq observes a cell with a nucleus, a cell wall, and chloroplasts, as well as other structures. What is he observing? 11. Which of the cell organelles stores water and other materials? 12. Which cell structure plays a role in cell transport? 13. How does cell transport help cells? 14. What is occurring when a relatively dry cell takes in water in a wet environment? 15. What happens when a cell reaches equilibrium with its environment? 16.
