                                  Photosynthesis summary

 Plants produce their own food by a chemical reaction called photosynthesis.
 Photosynthesis takes place in the chloroplasts of plant cells. They contain a green
 pigment called chlorophyll that absorbs the light energy needed for the reaction.

 Reactants – these are chemicals that               Products – these are chemicals that
 the plant needs for photosynthesis.                the plant makes by photosynthesis.
