Question

Development of female gamatophyte

Answer 1

Spores undergo cell proliferation and differentiation to develop into gametophytes. The major function of gametophyte generation is to produce haploid gametes. The female gametophyte, also referred to as the embryo sac or megagametophyte, develops within the ovule, which is found within the carpel's ovary.

Answer 2

DEVELOPMENT OF FEMALE GAMETOPHYTE

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

• The micropylar end of the nucellus a single cell is differentiated and it is the megaspore mother cell or megasporocyte.

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

• The diploid megaspore cell undergo meiosis to form four haploid megaspore.

• These four megaspore are arranged in linear tetrads.

• Out of the four megaspore the upper three megaspores at the micropylar end degenerates and disappears.

• The basal region will become the funicle.
