NEETBotanyMorphology of Flowering Plants
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The flower of mustard is described as epigynous. Reason (R): In mustard flowers, the gynoecium occupies the highest position while the other floral parts are situated below it. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is not correct
- D(A) is not correct but (R) is correct
Correct answer
D. (A) is not correct but (R) is correct
Step-by-step solution
The Assertion (A) is not correct because the flower of mustard is an example of a hypogynous flower, not an epigynous one. In epigynous flowers, the margin of the thalamus grows upward enclosing the ovary completely. The Reason (R) is correct because it accurately describes the arrangement of floral parts in mustard. In mustard (a hypogynous flower), the gynoecium occupies the highest position on the thalamus while the calyx, corolla, and androecium are situated below it, making the ovary superior. Answer: (A) is n
