NEET BIOLOGY

Detailed explanation-1: -The correct option is A Generative cell.

Detailed explanation-2: -Final answer: Male gametes in angiosperms are formed by the division of generative cells.

Detailed explanation-3: -Pollen grain is male gametophyte containing generative cell which divides mitotically to give rise to two male gametes. So, one microspore mother cell produces four pollen grain and each pollen grain produces two gametes, there eight gametes are produced by one microspore mother cell.

Detailed explanation-4: -A male gametophyte is a gamete producing haploid phase in a plant. In angiosperms, it is the pollen grains that are regarded as gametophytes.

Detailed explanation-5: -The generative cell divides mitotically to form the two male gametes. These two male gametes move together with the pollen tube towards the female gametophyte. The vegetative cell then gives rise to the pollen tube, a tubular protrusion from the pollen grain, which carries the sperm cells within its cytoplasm.
