Question

The megaspore divides mitotically, resulting in a female gametophyte or embryo sac

that differentiates into an egg and a central cell with two nuclei called the
a) generative cell:
b) pollen grain.
Oc) microspores.
O d)
d) endosperm.
e) polar nuclei.

Answer 1

The megaspore divides to form a female gametophyte or embryo sac that differentiates into an egg and polar nuclei.

Step-by-step explanation:

The correct answer is e) polar nuclei.

The megaspore, which is produced in the ovule of a plant, divides mitotically to form a female gametophyte or embryo sac. This embryo sac differentiates into an egg and a central cell with two nuclei known as polar nuclei. The polar nuclei eventually fuse with the sperm nucleus to form the endosperm, which is a tissue that provides nourishment to the developing embryo. Therefore, the correct option is e) polar nuclei.
