Gametogenesis
The gametogenesis process includes the formation of reproductive cells or sex cells in living organisms. In plants, it is carried throughout mitosis whereas, in animals, it is carried through meiosis. The formation of male and female gametes are the two basic steps that take place during the gametogenesis process.
Based on the living organism, the process of gametogenesis occurs in:-
Plants: It occurs by the meiotic division of diploid gametocytes. In higher plants, it happens along with sporogenesis.
Animals: It occurs by meiosis where gametes are formed from their diploid mother cells exist in organs called gonads.
Stages of Gametogenesis
The gametogenesis process occurs in three steps. They are as follows;
- Mitotic divisions together with cell growth of precursor germ cells.
- The happening of Meiosis I and Meiosis II for producing haploid daughter cells.
- Metamorphose haploid daughter cells for the production of functional gametes.
