Here is a tip:

Various materials within the cell and outside the nucleus are important in the overall functioning of the cell.

Explanation

The cytoplasm consists of important proteins, the cytosol, and its embedded membrane-bound organelles that are important for the normal functioning of the cell.

The cytosol consists of various soluble and insoluble substances such as ions and cell organelles that are important for maintaining various metabolic activities, osmoregulation, and other cell-signalling processes.

The cytoskeleton extends between the nuclear membrane and the cell membrane. It helps provide rigidity and structure to the cell.

Verified Answer

The cytoplasm is a term that collectively describes all components that lie within the plasma membrane, except the nucleus.

The cytosol is the fluid part of the cytoplasm, whereas the cytoskeleton is a network of filaments found within the cytoplasm.
