Question

What are cells present in a developed embryo sac of angiosperms. Named them andention the chromosome set found in them

Answer 1

The haploid megaspore inside the nucellus gives rise to the female gametophyte, called the megagametophyte. In gymnosperms, the megagametophyte consists of around 2000 nuclei and forms archegonia, which produce egg cells for fertilization

Answer 2

In seed plants, the ovule is the structure that offers ascend to and contains the female regenerative cells. It comprises of three sections: The integument, framing its external layer, the nucellus (or leftover of the megasporangium), and the female gametophyte (shaped from a haploid megaspore) in its middle.

The female gametophyte — explicitly named a megagametophyte—is additionally called the developing life sac in angiosperms. The megagametophyte delivers an egg cell with the end goal of preparation.
