Question

In angiosperms, functional megaspore develops into____

Answer 1

Megaspore:

1. The female gamete is known as megaspore.
2. The megaspore is larger than the pollen and produced by heterosporous (producing spores of different sizes) plants.
3. The megaspore is developed by the reduction division meiosis inside the megasporocyte (developing female gametophyte), this process is known as megagametogenesis or megasporogenesis.
4. It generates haploid spores.
5. The major difference between both the processes is that in megasporogenesis the diploid megaspore mother cell undergoes meiosis to form four haploid megaspores whereas in megagametogenesis the megaspore develops into a female gamete.
6. The megaspore is formed inside the embryo sac.

Final answer: In angiosperms, a functional megaspore develops into the embryo sac.
