Cellular communication is the function of the plasma membrane that allows it to respond to certain stimuli from outside the cell and hormones to bind to receptors.
<h3>What is plasma membrane?</h3>
It is a double layer of lipids that covers and delimits the cells, serving as a border between the inside and the outside of the cell, and also allowing a physicochemical balance.
<h3>Characteristics of plasma membrane</h3>
Enables the development of compartments; allows or rejects the entry and/or exit of particles; acts as a mechanical defense; and reacts to external signals and stimuli.
It reacts and transmits information inside the cell, starting certain biochemical processes: cell division, cell movement or the segregation of biochemical substances.
Therefore, we can conclude that the main characteristic of the plasma membrane, that is, its ability to allow or reject the entry of certain molecules into the cell.
