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 single-celled organisms that lack a well defined nucleus. Single celled organisms like bacteria and archaea are prokaryotic in nature.
Detailed explanation-3: -The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.
Detailed explanation-4: -Prokaryotes are simple organisms that lack membrane-bound organelles. Single-celled organisms consist of only one cell. They are also known as unicellular organisms. All prokaryotes are single-celled.
Detailed explanation-5: -Eukaryotic cells are cells containing membrane-bound organelles and are the basis for both unicellular and multicellular organisms. In contrast, prokaryotic cells do not have any membrane-bound organelles and are always part of unicellular organisms.
