APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Prokaryotes are microscopic organisms belonging to the domains Bacteria and Archaea, which are two out of the three major domains of life. (Eukarya, the third, contains all eukaryotes, including animals, plants, and fungi.) Bacteria and archaea are single-celled, while most eukaryotes are multicellular.

Detailed explanation-2: -The two prokaryote domains, Bacteria and Archaea, split from each other early in the evolution of life.

Detailed explanation-3: -Two of the three domains, Bacteria and Archaea, are prokaryotic.

Detailed explanation-4: -Only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes-pro means before and kary means nucleus. Animals, plants, fungi, and protists are all eukaryotes-eu means true-and are made up of eukaryotic cells.

Detailed explanation-5: -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.
