Question

How many blades are attached to each petiole in compound leaves?

Answer 1

Structure of compound leaves:

1. A compound leaf contains two or more leaflets originating from the same leafstalk.
2. It has a blade that is divided to the midrib; causing the leaf to form more than two separate leaflets.
3. There are multiple blades that are further attached to petioles.
4. The petiole is the stalk that connects the leaf to the stem part of the plant.
5. Further, they can be classified as pinnately or palmately compound leaves.
6. In palmately compound leaves, the leaflets emerge at the tip of the petiole. They can be unifoliate (one leaflet), bifoliate(two leaflets), trifoliate (three leaflets), quadrifoliate(four leaflets), multifoliate(many leaflets)
7. In pinnately compound leaves, the leaflets are connected along the common axis of the petiole. They can be unipinnate, bipinnate, tripinnate, paripinnate, decompound, and imparipinnate.
