Question

Leaves are a plant's major site of photosynthesis and gas exchange

with the atmosphere. True or False?

Answer 1

True

Step-by-step explanation:

The cells in a middle layer of leaf tissue called the mesophyll are the primary site of photosynthesis. Small pores called stomata—singular, stoma—are found on the surface of leaves in most plants, and they let carbon dioxide diffuse into the mesophyll layer and oxygen diffuse out.
