What is the fundamental difference in the structure of bacterial cells from the cells of plants, animals and fungi?

Bacteria are classified as prokaryotes, while plants, animals, and fungi are classified as eukaryotes. A prokaryotic cell is characterized by:

– the absence of a formed nucleus, that is, the nuclear envelope, nuclear juice and nucleoli. Genetic information is stored as a single circular chromosome, consisting only of DNA (no protein coat).

– the absence of all organelles characteristic of eukaryotes, except for small ribosomes. The functions of these organelles are performed by mesosomes – invaginations of the plasma membrane.

– division by amitosis.
