Plants perform photosynthesis, a chemical reaction that occurs in chloroplasts and uses chlorophyll to produce glucose and oxygen from carbon dioxide, water, and light energy. Photosynthesis takes place in plant leaves, where carbon dioxide enters and oxygen exits through small openings, while water and minerals are absorbed by the roots. The glucose produced is used by the plant for energy and building new tissues, or is released through respiration.

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.
