NEET · Biology · STD 11 - 5. Morphology flowering plants

Identify the type of flowers based on the position of calyx, corolla and androecium with respect to the ovary from the given figures (\(a\)) and (\(b\))

A (\(a\)) Hypogynous; (\(b\)) Epigynous
B (\(a\)) Perigynous; (\(b\)) Epigynous
C (\(a\)) Perigynous; (\(b\)) Perigynous
D (\(a\)) Epigynous; (\(b\)) Hypogynous

Verified Solution

Answer & Solution

Correct Answer

(C) (\(a\)) Perigynous; (\(b\)) Perigynous

Step-by-step Solution

Detailed explanation

If gynoecium is situated in the centre and other parts of the flower are located on the rim of the thalamus almost at the same level, it is called perigynous.
Both diagram shows perigynous condition.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
