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: -A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles.
Detailed explanation-3: -A prokaryote (/proʊˈkærioʊt, -ət/) is a single-celled organism that lacks a nucleus and other membrane-bound organelles.
Detailed explanation-4: -Prokaryotic cells only have a small range of organelles, generally only a plasma membrane and ribosomes. Eukaryotic cells, on the other hand, have chromosomes that are enclosed in a true nucleus, and are therefore separated from the cytoplasm by the nuclear membrane.
