Question

development of the femail Gametophyte

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

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

• These four megaspores are arranged in a linear tetrad.

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

• The remaining one of the tetrad at the chalazal end becomes functional megaspore.

• It enlarges and develops in to female gametophyte or embryo sac.

• The functional megaspore is the first cell of the female gametophyte.

• The haploid nucleus of the megaspore divides by three repeated mitotic division to form an eight nucleate female gametophyte or embryo sac.
