Male gametophyte in angiosperms produces

A single sperm and two vegetative cells
B three sperms
C two sperms and a vegetative cell
D single sperm and a vegetative cell.

Verified Solution

Answer & Solution

Correct Answer

(C) two sperms and a vegetative cell

Step-by-step Solution

Detailed explanation

(c) : The protoplast of the male gametophyte divides mitotically to produce two unequal cells — a small generative cell and a large vegetative cell. The generative cell divides later into two nonmotile male gametes (or sperms). Thus, the male gametophyte in angiosperms produces two sperms and a vegetative cell. The vegetative cell, later on, grows to produce pollen tube.

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.
