Question

When the leaflets are arranged laterally all along the length of the rachis like the plumes of a feather, the compound leaf is called as

• A. Unifolate palmately compound leaf
• B. Multifolate palmately compound leaf
• C. Bifoliate palmately compound leaf
• D. Pinnately compound

Answer 1

The correct option is D Pinnately compound

The leaf in which the lamina or leaf blade is completely broken into distinct leaflets is called compound leaf. The leaf has incisions which reach the midrib. Compound leaf contains a bud at the axil of the petiole but is absent in the axil of leaflets. The compound leaves are of two types: Pinnately compound lead and palmately compound leaf.

When the leaflets are arranged laterally all along the length of the rachis like the plumes of a feather, the compound leaf is called as pinnately compound leaf. In pinnately compound leaf, the midrib forms a common axis called rachis. These types of leaves are present in neem plant.

Pinnately compound leaves are of five types:

1. Unipinnate paripinate
2. Unipinnate imparipinate
3. Bipinnate
4. Tripinnate
5. Decompound
