notes

Cytoplasm:

It is a jelly like, viscous, colourless semi-fluid substance of cytoplasm called cytosol that contains a variety of cell organelles and other insoluble waste products and storage products like, starch, glycogen, lipid, etc.

Cell organelles are enclosed by membranes. In prokaryotes, beside the absence of a defined nuclear region, the membrane-bound cell organelles are also absent. On the other hand, the eukaryotic cells have nuclear membrane as well as membrane-enclosed organelles. The significance of membranes can be illustrated with the example of viruses. Viruses lack any membranes and hence do not show characteristics of life until they enter a living body and use its cell machinery to multiply.
