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 ovary in peach and plum is said to be half-inferior. Reason (R): In these flowers, the margin of the thalamus grows upward enclosing the ovary completely and getting fused with it. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- A(A) is true but (R) is false
- BBoth (A) and (R) are true and (R) is the correct explanation of (A)
- CBoth (A) and (R) are true but (R) is not the correct explanation of (A)
- D(A) is false but (R) is true
Correct answer
A. (A) is true but (R) is false
Step-by-step solution
Assertion (A) is true. Peach, plum, and rose have perigynous flowers, in which the ovary is said to be half-inferior. Reason (R) is false. The description provided in the reason (margin of thalamus grows upward enclosing the ovary completely and getting fused with it) is the exact anatomical definition of an epigynous flower (e.g., guava, cucumber), which has an inferior ovary. In perigynous flowers like peach and plum, the thalamus margin grows to form a cup-like structure but does not completely enclose or fuse w
