Observe the diagram and answer the question.
Identify the correct statements:
(A) Vegetative cell is bigger with irregular shaped nucleus compared to generative cell
(B) Vegetative cell divides mitotically to form two male gametes
(C) Generative cell divides meiotically to form four male gametes
(D) Generative cell divides mitotically to form two male gametes
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A) and (D) only
(A) Vegetative cell is bigger with irregular shaped nucleus compared to generative cell — True.
(B) Vegetative cell divides mitotically to form two male gametes — False. The generative cell forms the male gametes.
(C) Generative cell divides meiotically to form four male gametes — False. It divides by mitosis into two male gametes.
(D) Generative cell divides mitotically to form two male gametes — True.
NCERT Extract:
Stamen, Microsporangium and Pollen Grain – “… The vegetative cell is bigger, has abundant food reserve and a large irregularly shaped nucleus. The generative cell is small and floats in the cytoplasm of the vegetative cell. It is spindle shaped with dense cytoplasm and a nucleus. In over 60 per cent of angiosperms, pollen grains are shed at this 2-celled stage. In the remaining species, the generative cell divides mitotically to give rise to the two male gametes before pollen grains are shed (3-celled stage).”
