AIIMS 2019 Botany Flower Symmetry MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Which of the following represent zygomorphic symmetry

A

Canna, Mustard, Chilly, Datura

B

Mustard, Canna, Pea, Datura

C

Pea, Bean, Cassia, Gulmohar

D

Pea, Bean, Canna, chilly

Correct Answer

Option C

Detailed Explanation

Zygomorphic symmetry, also known as bilateral symmetry, is characterized by flowers that can be divided into two identical halves along a single plane. Option C (Pea, Bean, Cassia, Gulmohar) includes flowers that exhibit this type of symmetry, as they can be split into mirror-image halves. In contrast, the other options contain flowers with actinomorphic symmetry (radial symmetry), such as Canna and Mustard, which can be divided into multiple identical sections along several planes. Understanding these symmetry types is crucial for identifying and classifying flowering plants in botany.
