leaf

(lēf)
Noun
A flat, usually green plant part that grows on the stem and takes in carbon dioxide and sunlight to manufacture food by photosynthesis. Leaves consist of an outer tissue layer (the epidermis) through which water and gases are exchanged, a spongy inner layer of cells that contain chloroplasts, and veins that supply water and minerals and carry out food. Some leaves are simple, while others are compound, consisting of multiple leaflets.
