Hint: Prokaryotes are organisms that do not have a well-defined nucleus and membrane-bound cell organelles. They do not have an inner membrane which makes them different from the eukaryotes.
Complete answer:
All prokaryotes are unicellular and do not have a well-developed nucleus. Prokaryotes are divided into bacteria and archaea. Prokaryotes lack cellular compartments and therefore do not have membrane-bound organelles and lack mitochondria. This is why the cellular components of prokaryotic cells are enclosed in the cytoplasm except for the outer cell membrane. The bacterial microcompartments are enclosed in the protein shells that are the simple organelles and some prokaryotes which include the cyanobacteria that form large colonies being unicellular. Myxobacteria consist of multicellular stages in their life cycle and the prokaryotes are asexual which reproduce without the fusion of gametes and perform horizontal gene transfer.
They are composed of various shapes which include cocci which is a spherical or oval shape known as coccus seen in Streptococcus. A cylindrical shape known as a rod or a bacillus is also seen in the bacteria. Other shapes include some rods that are twisted into spiral shapes and are known as spirilla. A comma-shaped bacterium is known as vibrio. The bacteria reproduce using binary fission which is the asexual mode of reproduction and the genetic exchange takes place in a form of horizontal gene transfer which is not a replicated process and involves the transfer of DNA between two cells.
Note:
Prokaryotic cells are composed of cell walls which are present in plants and are used for protection as they are single-celled organisms. The genetic material of the prokaryotic cell is contained in a nucleoid.
