Leaf structure and photosynthesis

1. Leaf Structure and
Photosynthesis

2. Photosynthesis
• Green plants (producers) can use light
energy 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.

3. • 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 starch + oxygen
dioxide
Light energy
