Find the appropriate option which justifies all these statements. i. Protect the cell by acting as a barrier. ii. Regulates the transport of substances in and out of the cell. iii. Receives chemical messengers from other cells. iv. Acts as a receptor. v. Cell mobility, secretions, and absorptions of substances. (A) The nuclear membrane (B) Endomembranous system (C) Plasma membrane (D) All of these

Tardigrade Admin · Accepted Answer

The plasma membrane has lipid molecules consisting of a hydrophilic head and a hydrophobic tail made up of saturated and unsaturated fatty acid which provides quasi fluid nature to lipid. The membrane protects the cell by acting as a barrier and regulates the transport of substances in and out of the cell. For many of the chemical messengers from other cells these acts as a receptor and mediates the cell mobility, secretions, and absorptions of substances.
