(N/A) typical leaf consists of three main parts: the leaf base,the petiole,and the lamina (leaf blade).
$1$. Leaf base: The part of the leaf attached to the stem. It may bear two lateral small leaf-like structures called stipules.
$2$. Petiole: The stalk that holds the leaf blade to light.
$3$. Lamina (Leaf blade): The green,expanded part of the leaf with veins and veinlets. The middle prominent vein is called the midrib. The veins provide rigidity to the leaf blade and act as channels of transport for water,minerals,and food materials.
Additionally,an axillary bud is often present in the axil of the leaf,which later develops into a branch.
