Cytoplasm

The material present between the plasma membrane (cell membrane) and the nuclear membrane is called cytoplasm.

It is composed of cytosol (suitable part or the liquid matrix of cytoplasm), Inclusions (Insoluble wastes and storage products) and organelles (Mitochondria, Ribosome etc).

Chemical Composition:

It is about 90% water. It forms a solution containing all the fundamental molecules of life. In the cytosol, small molecules and ions may form “true solution,” and some large molecules form “colloidal solution.” Colloidal solution may be a sol (non-viscous) or a gel (viscous). Peripheral parts of the cell are often like a gel.

Function:

The cytoplasm of the cell provides space for the proper functioning of the organelles and also acts as the site for various biochemical (metabolic) reactions for example Glycolysis (breakdown of glucose during cellular respiration).
