Cytoplasm of bacteria

Basically, all animal cells can be divided into two major compartments, the nucleus and the cytoplasm. The cytoplasm (material in the cell interior) of all bacteria is enclosed within a cell membrane that itself is surrounded by a rigid cell wall.

Cytoplasm is about 80% water and contains primarily proteins (enzymes), carbohydrates, lipids, inorganic ions and many low MW compounds. Major structures in the cytoplasm are DNA, ribosomes and inclusions.

Functions of the cytoplasm
•Regulates exchange of material outside the cell
•Biosynthesis of macromolecules
•Generation of energy
•Cell movement

Components of the cytoplasm
•Cytoplasmic organelles
•Cytoplasmic inclusions
•Cytoplasmic matrix or cytosol

The presence of cell wall is essential to protect bacteria against destruction by osmotic pressure. The bacterial cytoplasm is much more concentrated with solutes than in most microbial habitats which are hypotonic.
