Pinnate and palmate compound leaves are two types of leaf venation. Venation is the arrangement of veins on a leaf blade. Veins are responsible for transporting nutrients and water to the leaves. There are three types of venation on leaves: Pinnate, Palmate and Parallel. The single middle vein is the primary vein, and the veins arriving from it are secondary veins. Let us now look at the differences between pinnately and palmately compound leaves:

FAQs
What is the difference between pinnate and bipinnate leaves?
Pinnate leaves are the ones that have a single primary vein from which multiple secondary veins arise, whereas bipinnate leaves are the ones in which the leaflets themselves are pinnately veined.
What is a toothed leaf?
It is a type of leaf where the margins have small points that look like teeth along it.
