What are Pinnately compound leaves?

What does a pinnate leaf look like?

Pinnately compound leaves will have twig-connecting petioles of varying lengths with rows of smaller sub-leaves above the axil. These leaflets form on either side of an extension of the petiole or rachis, and although they may look like several small leaves, each of these leaflet groups is actually considered one leaf.

How is a Pinnately compound?

Answer: In pinnately compound leaf, the number of leaflets are present on a common axis, the rachis, which represents the midrib of the leaf as in neem. In case of a palmately compound leaf, the leaflets are attached at a common point, i.e., at the tip of petiole as in silk cotton.

What is compound leaf?

Why is a leaf of neem called Pinnately compound?

Look at the nuts.
Look at the pith.
