Leaves can be divided into two types:
- Simple leaf
- Compound leaf
SIMPLE LEAF
- In a Simple Leaf, either the incisions are absent or if present, then do not reach the midrib.
- Axillary bud is present at the axil of petiole.
COMPOUND LEAF
- In a Compound Leaf, the incisions reaches the midrib and the lamina is divided into a number of leaflets.
- Axillary bud is present at the axil of petiole but absent at the axil of leaflets.
- Compound leaf are divided into two types on the basis of arrangement of leaflets:
PINNATELY COMPOUND
Number of leaflets are present on a common axis called Rachis which represents the midrib of the leaf.
PALMATELY COMPOUND
The leaflets are attached at a common point i.e. at the tip of the petiole.
