Detailed explanation-1: -The correct option is A Prokaryotes. Prokaryotes are single-celled organisms that lack a well defined nucleus. Single celled organisms like bacteria and archaea are prokaryotic in nature.
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. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.
Detailed explanation-3: -Bacteria are single celled microbes that lack a nucleus. Archaea are like bacteria, but they have different structures and properties. This gives them the ability to live in extreme environmental conditions. Protozoa are unicellular microorganisms that have nuclei.
Detailed explanation-4: -(bak-TEER-ee-uh) A large group of single-cell microorganisms. Some cause infections and disease in animals and humans. The singular of bacteria is bacterium.
Detailed explanation-5: -Single-celled organisms are called unicellular organisms. All prokaryotic organisms such as Bacteria, Archaea are unicellular. A single cell performs all functions such as metabolism, excretion and reproduction. They reproduce by asexual means.
