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 flowers of guava and cucumber are classified as epigynous. Reason (R): In guava and cucumber, 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 correct answer from the options given below:
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A)
- BBoth (A) and (R) are true but (R) is not the correct explanation of (A)
- C(A) is true but (R) is false
- D(A) is false but (R) is true
Correct answer
A. Both (A) and (R) are true and (R) is the correct explanation of (A)
Step-by-step solution
In epigynous flowers, the margin of the thalamus grows upward enclosing the ovary completely and getting fused with it, while the other parts of the flower arise above the ovary. This makes the ovary inferior. Guava and cucumber exhibit this exact morphological arrangement, which is the defining reason their flowers are classified as epigynous. Thus, both Assertion (A) and Reason (R) are factually true, and (R) provides the correct morphological explanation for the classification stated in (A). Answer: Both (A) and
