2. Photosynthesis Organisms make food using light energy

3. many kinds of organisms carry out photosynthesis Blue-green algae bacteria Multicellular plants

4. Plants provide food for animals, and us, too

5. Photosynthesis Needs co 2 & h 2 o Needs light energy Makes sugar Makes o 2 leaf

6. Photosynthesis equation 6CO 2 + 6H 2 O C 6 H 12 O 6 + 6O 2 Complex carbohydrates, proteins, fats, amino acids, enzymes, coenzymes, pigments

7. Light Energy – The the part we can see and the plants use!

8. PLANT PIGMENTS ABSORB CERTAIN WAVELENGTHS OF THE VISIBLE SPECTRUM (SUNLIGHT) Chlorophyll a Chlorophyll b phycoerythrin phycocyanin Beta-carotene

9. Plants are green because they reflect the green wavelengths and absorb (and use) the others. Your favorite blue shirt is blue because it reflects blue wavelengths and absorbs the other wavelengths …. Plants reflect green wavelengths.

10. The leaf is the primary photosynthetic organ of the plant

11. Leaves take in CO 2 while roots take in H 2 O

12. Chloroplasts are found in the cells of the leaf and other photosynthetic parts of the plant

13. Green plant cells contain chloroplasts

14. Photosynthesis occurs all day Photosynthesis occurs as long as light is available

15. Photosynthesis and respiration are interdependent upon each other – plants carry out both processes

17. goodnight

19. All organisms need energy

20. Why do we need energy? To Grow To Move To Reproduce ETC.

21. Respiration provides energy from food

22. Aerobic respiration requires oxygen Anaerobic respiration does not require oxygen

23. C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O + ATP Glucose + oxygen carbon dioxide + water + ATP Respiration occurs in the Mitochondria of Cells Aerobic Respiration Equation

24. Aerobic Respiration has three major steps 1  2  3  34-36 ATP

25. Respiration provides Energy from food so we can:
