Question

define plasma membrane and cell wall​

Answer 1

Answer:

Essentially, the plasma membrane refers to the cell membrane that defines the boundaries of a cell and cell organelles. As such, it forms a barrier, with controlled interaction, between two aqueous compartments; between the intracellular and intracellular environments.

A cell wall is defined as a rigid, external layer that is specifically designed to provide structural support and rigidity. It also keeps the interior components of the cell intact and safe from the external environment.

Explanation:

Answer 2

Since cell contains important materials for its living so it should have to protect its those important materials now for protecting its material cell forms two types of layers on the outermost part of its body one layer is living i.e supports for metabolism of cell and other layer is non-living i.e. doe not support metabolism of cell and its rigid. Now according to terminology living layer is known as PLASMA MEMBRANE and non-living layer is known as CELL WALL OR CELL MEMBRANE.
