Compound Leaves

Compound leaves are a type of leaf where the leaf blade is divided into multiple leaflets. Each leaflet is attached to the stem by its own stalk, called a petiole. Compound leaves can be further classified into two main types: palmately compound and pinnately compound.

Palmately Compound Leaves

In palmately compound leaves, the leaflets are attached at a single point at the tip of the petiole, resembling the fingers of a hand. Each leaflet is arranged like the fingers of a hand, radiating out from a central point.

Pinnately Compound Leaves

In pinnately compound leaves, the leaflets are arranged on either side of the petiole, resembling a feather. The leaflets are attached along the central petiole, and they can be arranged in a feather-like pattern.
