What are the ingredients?

1.

Light energy

2.

Water

3.

Carbon dioxide

The light energy splits the water molecules into hydrogen and oxygen.

Light energy Vs H2O H, O

CO2

The hydrogen joins with carbon dioxide to make sugar

CO2 + H Glucose

+H

O

= glucose

O

The sugar is carried to other parts of plant. The oxygen is release into the air.
