Detailed explanation-1: -In compound leaves, a blade has two or more subunits called leaflets: in palmately compound leaves, the leaflets radiate from a single point at the distal end of the petiole; in pinnately compound leaves, a row of leaflets forms on either side of an extension of…

Detailed explanation-2: -Compound leaves have their lamina separated into multiple leaflets. Compound leaves are of two types: Pinnately Compound Leaves – Here, leaflets are present on the common axis called the rachis. Leaves are arranged in the opposite manner.

Detailed explanation-3: -Part of the Biodiversity Counts Curriculum Collection. Twice pinnate: The leaflets are also divided into leaflets. Pinnate (even): Leaflets are attached along an extension of the petiole called a rachis; there is an even number of leaflets. Palmate: Leaflets are attached to the tip of the petiole.

Detailed explanation-4: -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-5: -A leaf which is divided into smaller leaflets, those leaflets arranged on each side of the leaf’s central stalk/rachis (axis).
