Describe the types of leaves.

(N/A) $\rightarrow$ There are two main types of leaves: $(i)$ Simple leaf,$(ii)$ Compound leaf.
$(i)$ Simple leaf: $A$ leaf is said to be simple when its lamina is entire or,when incised,the incisions do not reach the midrib.
$(ii)$ Compound leaf: When the incisions of the lamina reach up to the midrib,breaking it into a number of leaflets,the leaf is called compound. Compound leaves are classified into two types: pinnately compound and palmately compound.
$\rightarrow$ Pinnately compound leaf: In a pinnately compound leaf,a number of leaflets are present on a common axis called the rachis,which represents the midrib of the leaf,as seen in $Neem$.
$\rightarrow$ Palmately compound leaf: In palmately compound leaves,the leaflets are attached at a common point,i.e.,at the tip of the petiole,as seen in silk cotton.
