Gematogenesis occurring in animal and human cells is known as Spermatogenesis and Oogenesis. Spermatogenesis is a process of sperm Formation. It produces 4 sperm cells from 4 daughter cells of meiosis.
is a process of egg cell (ovum) formation. Oogenesis only Produces 1 egg cell of four possible daughter cells. In this case, another 3 Daughter cells undergo degeneration and shatter.
Gametogenesis. (a) 0ogenesis and (b) spermatogenesis.
Gametogenesis of plant cells is known as microsporogenesis and macrosporogenesis. Microsporogenesis is a formation process of male sex cell, white macrosporogenesis (megasporogenesis) is a formation process of female sex cell.
Meiosis of plant cell becomes important because it can maintain the number of chromosome of organism to remain diploid. It means when a male sex cell and female sex cell, each of which is haploid, merges, it will produce diploid organism.
The importance of meiosis. Because of meiosis, every organism born remains diploid.
Based on the explanation above, it can be concluded that in meiosis, there occurs chromosome reduction. Cell that has 2n chromosome (diploid) changes into n chromosome (haploid). Therefore, meiosis is also known as reduction division.
