Detailed explanation-1: -Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.
Detailed explanation-2: -Prokaryotes are unicellular organisms that are devoid of a nucleus and membrane-bound organelles. The prokaryotic cytoplasm carries the genetic material in the form of DNA which is usually round in shape.
Detailed explanation-3: -Interestingly, “prokaryote” means “before the nucleus, ‘’ and refers to a cell structure where the chromosomal DNA is not enveloped in any internal membrane but is free in the cell cytoplasm.
