part of leave. (with diagram)

Dear student,

A typical leaf consists of three main parts: leaf base, petiole and lamina.

Leaf base-The leaf is attached to the stem by the leaf base and may bear two lateral small leaf like structures called stipules.

Petiole-The petiole help hold the blade to light. Long thin flexible petioles allow leaf blades to flutter in wind, thereby cooling the leaf and bringing fresh air to leaf surface. 

Lamina- The lamina or the leaf blade is the green expanded part of the leaf with veins and veinlets.

Dear Student,

Each leaf typically has a leaf blade ( lamina ), stipules, a midrib, and a margin. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves.
