Question

Observe the following matches.
(i) Datura - Actinomorphic flower
(ii) Canna - Zygomorphic flower
(iii) Gulmohur - Zygomorphic flower
(iv) Cassia - Asymmetric flower
Which of these is/are correct?

• A. (i), (ii) and (iii)
• B. (i), (iii)
• C. (ii) and (iv)
• D. (ii), (iii) and (iv)

Answer 1

Answer: (B)

Flowers are classified into three on the basis of symmetry i.e.actinomorphic, zygomorphic, and asymmetry. When flowers can be cut from more than one axis to get always equal halves that are known as actinomorphic symmetry. When a flower can be cut through one axis to obtain equal halves is known as zygomorphic symmetry. The asymmetric flowers cannot be cut through any axis. So the correct answer is B because Canna is an asymmetric flower and Cassia is a Zygomorphic flower.
