Differentiate between in-situ and ex-situ approaches of conservation / of biodiversity.
The cell division involved in gamete formation is not of the same type in different organisms. Justify.
Cell division results in the formation of gamete, heterogametic species produce male and female Gametes. In plant, monera, fungi, algae and bryophytes gametes are haploid in plants body but it may arise either as haploid or diploid. Haploid gametes are produced by mitotic division.
While organism such as pteridophytes, gymnosperms, angiosperms and animals including human beings, the parental body is diploid, they undergo reduction division, to produce haploid gametes.
