2. LO. Biology Organization of Living Things Benchmark 3 Explain the process of food storage and food use in organisms.

3. Carbohydrate Fat Protein Nucleic Acid

4. Cellular Respiration Splitting glucose in the cytoplasm Burning food in the mitochondria when oxygen is present Releasing ATP energy Producing carbon dioxide as a waste product

5. Mitochondria

6. PHOTOSYNTHESIS Converting light energy into food Exciting electrons in chlorophyll to reduce Carbon dioxide to glucose (sugar) Using water to replace electrons in chlorophyll Giving off oxygen as a waste product

7. Chloroplast

8. Cellular respiration Photosynthesis Oxygen, sunlight, carbon dioxide, carbohydrate, fat, protein, minerals, water. How organisms grow How plants store food How food and oxygen are distributed to cells The sun as the ultimate source of energy for organisms Energy transformations Key Concepts

9. Food storage such as maple tree—maple sapsuch as maple tree—maple sap, potato—starch honey bee—honey, cow—beef, milk Weight gain and weight loss. Change in respiration rates with exercise. Real-world Contexts http://www.biorap.org/br9/br9infact.html

11. http://www.umext.maine.edu/onlinepubs/PDFpubs/7036.pdf How to tap maple trees and make maple syrup?

12. Select and put in sequence the following phenomena involved in photosynthesis: 1. production of carbon dioxide and carbohydrates 2. production of oxygen and carbohydrates 3. exposure to light 4. breakdown of proteins 5. intake of carbon dioxide 6. intake of oxygen A. 3-4-13-4-1 B. 4-3-24-3-2 C. 3-5-23-5-2 D. 3-6-13-6-1

13. A. 3-4-1 incorrect: photosynthesis uses carbon dioxide, it doesn’t produce it Return to the question

14. B. 4-3-2 Incorrect: photosynthesis doesn’t involve the breakdown of proteins Return to the question

15. C. 3-5-2 Correct Return to the question

16. D. 3-6-1 Incorrect: photosynthesis doesn’t take in oxygen, it produces it Return to the question
