Question

The cell division involved in gamete formation is not of same type in different organism justify

Answer 1

 Cell division results in the formation of gamete, heterogametic species produce male and female gametes. In Monera, Fungi, Algae and Bryophytes gametes are haploid (n), the gametes are produced by mitotic division. While organism such as pteridophytes, gymnosperms, angiosperms and animals including human beings, the parental body is diploid (2n), they undergo reduction division, to produce haploid gametes.

Hope it helps ya!!

Answer 2

${\underline{\bold{\red{Answer :-}}}}$

In haploid organisms, gametes form by mitosis and diploid organisms do meiosis for the formation of gametes, in haploid organisms meiosis happens to maintain haplontic life cycle it does meiosis after fertilization. So gamete formation is not the same in a different organism.
