Question

A compound leaf with more than three pinnate nature is,
(a) Multifoliate
(b) Decompound
(c) Quadrifoliate
(d) Tripinnate

Answer 1

Hint: It has divisions that are themselves compound. This is the term used to denote the number of times the leaves are multiplied. Otherwise, it can also be said that a leaf consists of a typical stalk of a number of leaflets.

Complete step by step answer:
Decompound leaves are leaves that have been compounded more than once. The leaf with a pinnate or bipinnate nature of more than three is usually called a decompound leaf. It's a highly fractured leaf.
The best example of this type of leaf is ‘Coriander’. It is used in food as a garnish and some other recipes.
So, the correct answer is ‘Decompound’.

Additional information: There are two types of compound leaves, namely, pinnate compound leaves and palmate compound leaves. The leaflets are arranged at the tip of the petiole in the palmate compound leaf. Depending on the number of leaflets present at the tip of the petiole, it is further divided into 5 kinds. In the unifoliate, at the top of the petiole, only one terminal leaflet is attached. Citrus is an example. Two leaflets are connected side by side at the terminal end of the petiole in bifoliate. Aegle Marmelos is an example. Four leaflets are affixed to the tip of the petiole in the quadrifoliate. Paris quadrifolia is included, for example. Five or more leaflets, in multifoliate shape, are found at the tip of the petiole in the shape of palm fingers. Examples include Malabarica from Bombax.

Note: Simple leaves have a single leaf blade or lamina, whereas compound leaves have leaflets called smaller and different leaf blades. The base of the simple leaf includes stipules, but the stipules are present at the base of the leaf in the compound leaf, but other extra structures are absent.
