2. Ingredients for Photosynthesis Water – enters plants through the roots Sunlight – captured by the chloroplast Carbon dioxide – (CO 2 )enters the leaf through the stoma (pores)

3. Products of Photosynthesis Oxygen (O 2 ) – released as a waste product Glucose (C 6 H 12 O 6 ) – carbohydrate used for food

4. Tell the 3 ingredients of photosynthesis.Tell the 3 ingredients of photosynthesis. Tell the 2 products of photosynthesis.Tell the 2 products of photosynthesis.

5. Formula for Photosynthesis 6CO 2 + 6H 2 O light C 6 H 12 O 6 + 6O 2 Notice, ingredients go on the left, products go on the right. The arrow is like an equal sign. If energy needs to be added to a reaction for it to occur, it goes above the arrow.

6. Why is light written above the arrow in the formula?Why is light written above the arrow in the formula?

7. Steps of Photosynthesis Phase 1 – Light Reaction 1.Light hits the chloroplast. 2.Light energy breaks water into H and O. 3.O 2 is released as a waste product.

8. Phase 2 – Calvin Cycle 4. CO 2 enters the leaf through the stoma. 5. CO 2 and H combine to produce C 6 H 12 O 6.

9. What are the 2 phases of photosynthesis?What are the 2 phases of photosynthesis? Describe each phase to your partner.Describe each phase to your partner.

10. ATP isn’t stable enough to store energy long term, which is why energy is stored as glucose. Glucose stores energy much more efficiently than ATP.
