What is a prokaryotic cell?

Prokaryotic is made up of two words. Pro + karyon in which pro means primitive and karyon means nucleus.

Those cells in which a primitive nucleus is found, or a distinct nuclear envelope is not found, or a nucleus is not found, then such cells are called prokaryotic cells.

Definition of prokaryotic cell -

There are three types of prokaryotic cells.

How many types of prokaryotic cells?

There are bacteria, blue-green algae (cyanobacteria), and mycoplasma, and mycoplasma is placed within a group called Pleuro Pneumonia Like Organisms (PPLO).

Now you must be wondering why mycoplasma has been kept in PPLO.

Because the cell wall is found in bacteria and blue-green algae and the cell wall is not found in mycoplasma.

Due to the lack of cell walls in mycoplasma, its shape is not fixed. Therefore, in prokaryotic cells, those that do not have a definite shape are placed in the PPLO group.

Prokaryotic cells are much smaller than eukaryotic cells. And it is simpler than the eukaryotic cell, due to which the prokaryotic cell divides very rapidly.
