Protecting the integrity of the interior cell.
Providing support and maintaining the shape of the cell.
Helps in regulating cell growth through the balance of endocytosis and exocytosis.
The cell membrane also plays an important role in cell signalling and communication.
It acts as a selectively permeable membrane by allowing the entry of only selected substances into the cell.
Fluid Mosaic Model
It is composed of the following constituents:
Following are the important difference between the cell membrane and plasma membrane:
It surrounds the entire components of the cell.
It surrounds only the cell organelles.
It regulates the tonicity of the cell.
It does not regulate the tonicity of the cell.
The cell membrane can be transformed to stimulate movement and feeding in organisms such as Paramaecium.
The plasma membrane cannot be modified.
It contains initial receptors for signal transduction and is the first step in cell signalling.
It is not the first step in cell signalling. However, it is involved in the process.
Always protects the cell from bacteria and viruses.
Does not always protect the cell from outside invaders.
Plays an important role in cytokinesis during cell division.
Do not play a key role in cytokinesis during cell division.
Cilia are present and are involved in feeding and movement.
Cilia are absent.
