1. TOPIC: Plants Aim: Explain the process of photosynthesis. Do Now: Explain the two types of nutrition. HW:

3. Photosynthesis Process in which LIGHT energy is converted into CHEMICAL energy (food) Autotrophic nutrition

4. Occurs in chloroplasts

5. –Contain chlorophyll = green pigment that absorbs light A B C F E D

7. Equation Carbon + dioxide wateroxygen glucose + water + light Chlorophyll light 6CO 2 +12H 2 O C 6 H 12 O 6 +6H 2 O +6O 2 Chlorophyll (food) (wastes)

10. Light http://www.phschool.com/science/biology_place/biocoach/photosy nth/action.htmlhttp://www.phschool.com/science/biology_place/biocoach/photosy nth/action.html Most effective: blue & red –Easily absorbed

11. Least effective = green –reflected

12. What is the glucose used for? Respiration (aerobic) Glucose ATP

16. Why are plants important to living things?

17. 1. Produces food for itself & all other organisms (food chains)

18. 2. Removes CO 2 from the air & adds O 2
