Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R:
Assertion A: The ovary in hypogynous flower is said to be inferior.
Reason R: In the hypogynous flower the gynoecium occupies the highest position while the other parts are situated below it.
In the light of the above statements, choose the correct answer from the options given below:
A is false but R is true.
— Concept: This question tests your understanding of floral morphology, specifically the position of the ovary relative…Concept: This question tests your understanding of floral morphology, specifically the position of the ovary relative to other floral parts, and the terms associated with it (hypogynous, epigynous, perigynous).
Why (B) is correct:
Assertion A is false: In a hypogynous flower, the ovary is superior, meaning it is positioned above the other floral parts (sepals, petals, stamens). An inferior ovary is characteristic of epigynous flowers.
Reason R is true: In a hypogynous flower, the gynoecium (female reproductive part, including the ovary) occupies the highest position on the thalamus, and the other floral parts (sepals, petals, stamens) are situated below it. This arrangement leads to a superior ovary.
Why other options are wrong:
A) This is incorrect because Assertion A is false.
C) This is incorrect because Assertion A is false.
D) This is incorrect because Assertion A is false.
Common Mistake: Students often confuse the terms hypogynous, perigynous, and epigynous and the corresponding ovary positions (superior, half-inferior, inferior).
NEET Tip / Mnemonic: Remember "Hypo-Superior" (Hypogynous = Superior ovary) and "Epi-Inferior" (Epigynous = Inferior ovary). Perigynous is in between, with a half-inferior ovary.
Correct Answer: (B)
A is false but R is true.
