definition of prokaryotic cell

Prokaryotic cells are known as those cells that do not have a differentiated cell nucleus in their composition and their DNA is scattered throughout the cytoplasm, which is that part of the cells that houses the cellular organelles and facilitates their movement.

On the contrary, cells that do observe nuclei are designated as eukaryotes and they turn out to be, unlike the previous ones, the most popular and complicated life forms that exist.

Organisms that are made up of prokaryotic cells are mostly known as single-celled organisms.

Another big difference between prokaryotes and eukaryotes is that their metabolisms turn out to be widely varied, arriving to withstand very harsh environmental conditions in terms of temperature and acidity.

There is a strong belief that all living organisms today have a unicellular origin, which, through the years and through a long and slow process of evolution, led to a more complex type of cells, such as eukaryotes, almost surely as a consequence of the combination in the same cell of two or more prokaryotes.

Among the ways through which these cells they feed stand out the chemo synthesis, which involves the transformation of molecules and nutrients into organic matter by the method of oxidation of inorganic molecules. And the photosynthesis, which is the process through which some plants, algae and bacteria apprehend and use the energy that light shows, converting inorganic matter into organic, something vital and essential for their development.

Meanwhile, prokaryotic cells can reproduce asexually, that is, by bipartition. Each cell will split in two, with the previous division of the nucleus and the subsequent separation of the cytoplasm.

Or by conjugation, which supposes a procedure for sexual in which the gametes are temporarily fused, transferring genetic material from the person who exercises the role of donor to the recipient.

Depending on the form they manifest, there are various types of prokaryotic cells, including: coco, bacilli, vibrio, and spirilla.
