Detailed explanation-1: -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-2: -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.
Detailed explanation-3: -Bacteria are prokaryotic and unicellular organisms. The cell wall of bacteria is made up of peptidoglycan layer, and they lack membrane-bound organelles. The bacterial cell has a simpler organisation of structure. Hence, the given statement is false as bacteria are not eukaryotic organisms.
Detailed explanation-4: -Prokaryotes are generally unicellular organisms like bacteria. Prokaryotic cells do not have a well defined nucleus. Their genetic material is called a nucleoid. Membrane bound cell organelles are absent.
