Question

Which of the following is an example of actinomorphic flower?

• A. Datura
• B. Cassia
• C. Pisum
• D. Sesbania

Answer 1

The Correct Option is A

An actinomorphic flower, also known as a radial symmetrical flower, is one that can be divided into equal halves along multiple planes. This symmetry is akin to a circle or a star where any plane passing through the center will divide the flower into identical parts.

Let's review the characteristics of flowers given in the options:

• Datura: Datura flowers are indeed actinomorphic. They have a radial symmetry that allows them to be split into equal halves in multiple ways.
• Cassia: Flowers of Cassia genus, like Cassia fistula, are zygomorphic, meaning they have bilateral symmetry and only one plane that divides them into mirror-image halves.
• Pisum: Commonly known as the pea plant, its flowers are zygomorphic. They exhibit bilateral symmetry, meaning they can only be divided into mirror halves by a single plane.
• Sesbania: Like Pisum, Sesbania flowers also show zygomorphic attributes with bilateral symmetry.

Therefore, among the options provided, Datura is the correct example of an actinomorphic flower.
