Leaves: Classification, Structure and Function

Leaves: Classification, Structure and Function. Functions a.) Photosynthesis - l eaves are the main photosynthetic organs of most plants (some green stems are also photosynthetic.) - flat, wide leaves have a lot of SA to trap sunlight. - upper surface of leaf is chlorophyll rich.

Stomata observation

Stomata observation. Background. Stomata are found on the epidermal layer of a plant, and they consist of 2 guard cells and a small opening, a stoma. The primary function of the stomata is gas exchange, allowing CO 2 to enter the plant, and for water vapor and oxygen to escape. Procedure.
