Question

Identify the correct pair of plants with an odd number of leaflets in a compound leaf.
A. Hardwickia, Gynandropsis
B. Citrus, Aegle marmelos
C. Marsilea, Gynandropsis
D. Aegle marmelos, Hardwickia

Answer 1

Hint: It can be found based on the odd number of leaflets in the leaf, or as well as through the types of compound leaves. Compound leaves are those which have a greater number of leaflets. Through this, we can analyze the odd number of leaflets in a compound leaf.

Complete answer:
Here, the answer is found based on the number of leaflets. As Compound leaves have many numbers of leaflets, it can be easily divided based on numbers. Compound leaves are classified into two types. They are:
-Pinnately compound leaf
-Palmately compound leaf
PINNATELY COMPOUND LEAF: It contains an odd number of leaflets. This is due to the terminal leaflet at the tip of the petiole. The leaflets in this leaf are attached along the rachis. Example: Walnut
PALMATELY COMPOUND LEAF:
It contains even numbers of leaflets. The leaflets in this leaf are radiating outwards from the petiole. Here, all leaflets are not attached at the tip of the petiole. Example: Poison ivy
So, from here we are getting to know that citrus and aegle marmelos are coming under a pinnately compound leaf.
So, the correct answer is “Option b”.

Additional Information:
CITRUS:
-It is usually a spiny shrub, which comes under the genus citrus and family rutaceae.
-It is a fruit like grapefruit, orange.
-It is grown and cultivated mostly in southeast Asia.
-These are the edible fruits.
AEGLE MARMELOS:
-It is also known as BAEL, which is known as Bengal quince, wood apple, stone apple.
-These species are much popular in southeast Asia. It is present in Sri lanka.
-This tree is considered sacred for Hindus.

Note:
Pinnately compound leaf consists of five types. In that, Citrus lies under unifoliate leaves which contain single leaf and Aegle marmelos lie under trifoliate leaves which contain three leaves. The number of leaflets are odd
