Section 3 Photosynthesis

​

​

The process in which plants make their own food.

Sunlight(energy) and carbon dioxide(CO2) enter the plant's leaves.

Water(H2O) enters the plant's roots.

Sunlight helps chloroplasts in the plant cells break apart these compounds. The elements rearrange to form new compounds.
