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: -Bacteria are prokaryotes, lacking well-defined nuclei and membrane-bound organelles, and with chromosomes composed of a single closed DNA circle.
Detailed explanation-3: -Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles.
Detailed explanation-4: -Definition: A cell that lacks a nucleus enclosed within a nuclear envelope and membrane-bound organelles such as mitochondria. Prokaryotes are single-celled life forms. They include bacteria as well as archaea, which resemble bacteria but also share genetic and biochemical features with eukaryotes.
Detailed explanation-5: -Prokaryotes do not have a nucleus, so hence do not have a nucleolus.
