What is Prokaryotic Cell?
The prokaryotic cells were discovered by the scientists Antonie van Leeuwenhoek and Robert Hook. The prokaryotic cells are represented by bacteria, blue-green algae, mycoplasma and PPLO (Pleuro Pneumonia Like Organisms). They are generally smaller and multiply more rapidly than the eukaryotic cells. They may vary in shape and size. They are structurally simple and lack a true nucleus. There is no well-defined nucleus. The genetic material is not enveloped by a nuclear membrane. They also contain ribosomes for protein synthesis and a plasma membrane that surrounds the cell. Prokaryotes often have flagella for movement and pili for attachment. These cells can thrive in a wide range of environments and play essential roles in various ecological processes, including decomposition, nitrogen fixation, and disease.
Prokaryotic Cells
Prokaryotic cells are single-celled organisms that lack a true nucleus and membrane-bound organelles. Their genetic material is present in a nucleoid region. They are normally smaller than eukaryotic cells, with a size range of 0.1 to 5 μm in diameter. Prokaryotic cells for example bacteria and archaea have a cell wall and fimbriae and pili can often be found on the surface of bacterial cells. They evolved before the eukaryotic cells and live in nearly all environments on Earth. They have the ability to adapt to diverse environments.
