T. S. Leaf of Monocot & Dicot

The Lamina part of the leaf when used for taking longitudinal section will show three major divisions called as epidermal layer, mesophyll layer and vascular system. Epidermis layer will be present on the upper as well as lower surfaces of the leaf while these layers are covered by another thin casing called as cuticle. The stomata number are found to be more in the lower epidermis than in the upper. Sometimes, the upper epidermal layer might not have stomata at all.
