Explanation: 

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: -By definition, prokaryotes lack a membrane-bound nucleus to hold their chromosomes. Instead, the chromosome of a prokaryote is found in a part of the cytoplasm called a nucleoid.

Detailed explanation-3: -Prokaryotic cells have no membrane-bound organelles.

Detailed explanation-4: -A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles.

Detailed explanation-5: -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.
