Plants!
Chloroplast: organelle
Chlorophyll: green pigment
Pigment: substance that reflects some light and absorbs the rest
Photosynthesis Process where plants take in light,
water, and carbon dioxide (CO2) and make food
Importance of PS: That’s how every-thing gets energy!
Photosynthesis equation CO2 + H20 + light sugar + oxygen Only happens in green parts Food made is stored in roots and
leaves
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
Stoma/ stomata: opening on underside of leaves; allows for gas exchange
Oxygen and water lost thru them Open during day, closed at night
2. Light Independent reaction: doesn’t use light
–Glucose is made (sugar)
