Leaf structure, description, and modifications.
Leaf structure, description, and modifications. Leaves, which are initiated as primordia by the apical meristems, are vital to life as we know it because they are the principal sites of photosynthesis on land, providing the base of the food chain. Leaves expand by cell enlargement and cell division at the apical meristem. Most leaves are…
