NEET BIOLOGY

Detailed explanation-1: -Solution : Biologists are not sure about how many prokaryotic species there might be. The problem is that conventional taxonomic methods are not suitable for identifying microbial species and many prokaryotic species are simply not culturable under laboratory conditions.

Detailed explanation-2: -Solution : It is difficult to estimate climate diversity of prokaryotes because conventional taxonomic method are not suitable for identifying microbial species. Many of these species cannot be cultured under laboratory conditions. Biochemical & molecular biology techniques would put their diversity into millions.

Detailed explanation-3: -The prokaryotes have no diversity defined by the ecologist because it does not performs sexual reproduction. Explanation: The prokaryotes performs asexual reproduction in which no gamete formation is required. There is no need of fusion of gametes from the male and female parent cells.

Detailed explanation-4: -But these numbers do not include the number of species belonging to Kingdom Monera (prokaryotes). The reasons being: The conventional taxonomic methods are unable to identify and classify prokaryotic species. Many prokaryotic organisms are impossible to culture in vitro and hence cannot be studied properly.

Detailed explanation-5: -Conventional methods are not suitable for the bacterial biodiversity assessment due to the following reasons: Biochemical and morphological tests are the conventional methods to assess bacteria. Many bacteria cannot be cultured under normal conditions in the laboratory.
