Question

give an account of female gametophyte. ​

Answer 1

Explanation:

Female gametes are also known as eggs or ova. They are haploid cells that, when fused during sexual reproduction with a male gamete (sperm), form a zygote. Let's break this down a little more. During sexual reproduction, two cells - one from a female organism and one from a male organism - fuse together to create a zygote, or a fertilized cell. This zygote will mature into a new individual of the same species as the mother and father.

The female gamete is considered a haploid cell because it only has a half-set of chromosomes. When it fuses with the sperm of another haploid cell, their chromosomes come together to complete the set, resulting in a diploid zygote, which has a full set of chromosomes.

Answer 2

DEVELOPMENT OF FEMALE GAMETOPHYTE

• Development of ovule upto the formation of megaspore is called megasporogenesis.

• The ovule arises as a small projection of homogeneous tissue on the placenta in the ovary.

• The projection elongates rapidly and develops into multicellular nucellus.

• The basal region will become the funicle.

• The integuments arises as rim like out growth from the base of the nucellus.

• The integuments cover the nucellus leaving a small part at the top called micropyle.

• At the micropylar end of the nucellus, a single cell is differentiated.

• It is the megaspore mother cell or megasporocyte.
