6. Know and describe the function of leaves in the life of a tree.
A leaf is the part of a plant specialized for photosynthesis. For this purpose, a leaf is typically flat and thin, to expose the cells containing chloroplast to light over a broad area, and to allow light to penetrate fully into the tissues. Leaves can store food and water.
