Question

Appreciate the role of plasma membrane

Answer 1

The plasma membrane is the boundary between the cell and its environment. It regulates what enters and exits the cell. Cells must maintain an appropriate amount of molecules to function inside them. They must also have a way to keep things out or to allow things to enter. This is the job of the plasma membrane. The plasma membrane is like the guard at a gated community. The guard must inspect those who enter and those who leave to make sure that only the people and things needed in the community are there.

Answer 2

plasma membrane protects the cell and is selectively permeable to ions and organic solvents and hence helps in movement of molecules in and out of the cell.
