Prokaryotes are United in one Kingdom - Drobinki. To this Kingdom also includes blue-green algae and bacteria.
Prokaryotic cells are much less eukaryotic. Their size does not exceed typically 10 microns.
Circular DNA in prokaryotes is located in the center of the cell and does not have a shell. It is located in the cytoplasm. Eukaryotes, on the contrary, DNA stored in the nucleus, which is absent in their predecessors.
Eukaryotes and prokaryotes outside covered with plasma membrane. In prokaryote cells missing EPS - endoplasmic reticulum, plastids, mitohondrii, lysosomes and the Golgi complex. The function of these membrane organelles perform mesosoma.
Eukaryotes typically are aerobic. They use oxygen in energy metabolism. Prokaryotes, by contrast, are anaerobic and oxygen is harmful.
Prokaryotic cells reproduce asexually. In other words, they share. Their DNA doubles and the cell divides in half in the transverse plane. Such cells are able to divide every 20 minutes, but it is only in favorable conditions, which can not be.
Prokaryotes also do not have the digestive vacuoles, are not capable of mitosis and meiosis and gametes.
