2. Amount of food stored

3. Internal structure of leaf

Answer 2

ESSENTIAL RAW MATERIALS FOR PHOTO SYNTHESIS

1— CARBON DIOXIDE CO2 The carbon dioxide enters the leaves of the plant through stomata, which it subsequently convert to carbohydrates

An increase in the concentration of carbon dioxide in the atmosphere gives an increase in the rate of photosynthesis.

2—WATER H2O water is transported through the xylem vessels.

3—LIGHT In red coloured light the rate of photosynthesis is maximum whereas in green coloured light photosynthesis does not occur
