Detailed explanation-1: -Pinnately compound leaves can be unipinnate, bipinnate, tripinnate, etc. In the bipinnate compound leaves, the primary rachis is branched and leaflets are present on secondary rachis. Palmately compound leaves – In these types of leaves, leaflets are attached at the common point, i.e. the tip of the petiole.

Detailed explanation-2: -Compound leaves are of two types: Pinnately Compound Leaves – Here, leaflets are present on the rachis (common axis), which represents the midrib. E.g. Neem leaf. Palmately Compound leaves – Here, leaflets are attached together at one point, i.e. petiole tip.

Detailed explanation-3: -Compound: The leaf is separated into distinct leaflets, each with its own small petiole (but without an axillary bud). Simple: The leaf may be lobed or divided, but does not form distinct leaflets.

Detailed explanation-4: -There are three types of compound leaves: pinnately, double pinnately, and palmately.
