Protist /Fungi and Photosynthesis/Cellular Respiration Review

1. Protist/Fungi and Photosynthesis/Cellular Respiration Review

2. 1. Name one thing protists and bacteria have in common. Name two things that are different about protist and bacteria. • 1 thing….. Cell walls? Cilia? Flagella? How they reproduce? • 2 things…. Protists may be single-celled organisms or multicelled. Bacteria are only single-celled. Bacteria have no membrane bound organelles, protists have nuclei and other organelles. Protists are eukaryotic, while bacteria are prokaryotic

3. 2. How are protists classified? How do fungi-like protists get their nutrients? How do plant-like protists get their nutrients? How do animal-like protists get their nutrients? • Protists are classfied by how they get their food. (plant-like (photosynthesis), animal-like (heterotrophs), Fungi-like (heterotrophs that absorb their food.)

4. 3. What are flagella? What are cilia? Flagella are whip-like structures used for movement. Cilia are tiny hair-like projections that are used for movement.

5. 4. List four characteristics of fungi. What important role do fungi play for our environment? • 4 characteristics of fungi… • Heterotrophic • Reproduce by spores • Cell walls made of CHITIN • Eukaryotic • Multicellular • Fungi are DECOMPOSERS or SAPROBES

6. 5. What are three things that plants and fungi have in common? • 3 things that plants and fungi have in common….. • Eukaryotic • Have cell walls • multicellular

7. 6. Define autotroph. Define heterotroph. Autotroph – make their own food Heterotroph – get their food from consuming or absorbing other organisms.

8. 7. What is ATP? How is energy released from ATP? Explain why it can be said that ATP is a reusable battery? • ATP: The molecule of energy • Energy is released from the bond between the 2nd and 3rd phosphate. • ATP is constantly recycled from ADP

9. 8. Explain the process of photosynthesis. Write out the chemical equation.

10. 9. What are the reactants needed for photosynthesis? What are the products? PRODUCTS REACTANTS

11. 10. Where do the reactants needed for photosynthesis come from? How are the products of photosynthesis used?

12. 11. In what organelle does photosynthesis occur? Do both plants and animals perform photosynthesis? • ONLY plants and blue-green algae undergo photosynthesis.

13. 12. What are three factors that can affect the rate of photosynthesis? • Amount of light • Available water • Available CO2

14. 13. What most likely caused the formation of bubbles? • Oxygen…. • The plant used the CO2 in the flask to create oxygen.

15. 14. What is cellular respiration? Write out the chemical equation.

16. 15. What are the reactants needed for cellular respiration? What are the products? REACTANTS PRODUCTS

17. 16. Where do the reactants needed for cellular respiration come from? How are the products of cellular respiration used? • Reactants: Come from food, air and water • Products: are used for energy and as waste

18. 17. In what organelle does cellular respiration occur? Do both plants and animals perform cellular respiration? • Mitochondria • BOTH plants and animals perform cellular respiration.

19. 18. Why is cellular respiration called an aerobic process? What process will the body enter into if there is not enough oxygen to meet the demand? • It’s called an Aerobic process because OXYGEN is needed. • Without Oxygen, the process shifts to Anaerobic Fermentation.

20. 19. 1 molecule of glucose will make ___36______ molecules of ATP during cellular respiration.

21. 20. Explain why it is said that cellular respiration and photosynthesis are almost opposite processes?

22. 21. Photosynthesis and cellular respiration help to cycle ____CO2___, ____WATER______, and ____OXYGEN______ through ecosystems

23. 22. Photosynthesis ____creates_______ energy and Cellular respiration ______releases_________ energy.
