Leaf Structure and Photosynthesis

Standard Grade Biology

Photosynthesis

• Green plants

energy (producers)

can use

light

to make their own food • This process is called

photosynthesis

• Green plants are green because they contain a chemical called

chlorophyll

. This chemical is used to trap light energy.

• Chlorophyll is contained in the

chloroplasts

of plant cells • Light energy is used to change

carbon dioxide

and

water

into

starch

and

oxygen

• The word equation for photosynthesis is carbon + water dioxide Light energy starch + oxygen
