Simple and compound leaves

Simple Leaf: A leaf is said to be simple in which the leaf blade or lamina is
entire. It may be with incision or without incision. e.g. Mango

Compound leaf: Here the lamina is divided in to a number of leaf like lobes
called the leaflets. The leaflets are borne on a common axis and they do not bear
any axillary buds in their axils.

Four Type of Phyllotaxy(Leaf Arrangement)

Alternate phyllotaxy: In this type the leaves are arranged alternatively in the nodes. There is only one leaf at each node.

Opposite Phyllotaxy: In this type of arrangement two leaves are present at each node, lying opposite to each other.

Ternate Phyllotaxy : In this type there are three leaves attached at each node eg. Nerium

Whorled : In this type, more than three leaves are present in a whorl at each node eg. Alamanda.
