1. Plants!

2. Chloroplast: organelle

3. Chlorophyll: green pigment  Pigment: substance that reflects some light and absorbs the rest

4. Photosynthesis  Process where plants take in light, water, and carbon dioxide (CO 2 ) and make food Importance of PS: That’s how every- thing gets energy!

5. Photosynthesis equation  CO 2 + H 2 0 + light  sugar + oxygen  Only happens in green parts  Food made is stored in roots and leaves

6. Two parts to PS 1. Light dependent reaction: -- Light energy makes water split (the Hydrogen is used to make food) –The oxygen is released as waste

7.  Stoma/ stomata: opening on underside of leaves; allows for gas exchange  Oxygen and water lost thru them  Open during day, closed at night

8. 2. Light Independent reaction: doesn’t use light –Glucose is made (sugar)

9. Structure of a Leaf
