Cell Membrane/Plasma Membrane | Cell-Structure & Function | Biology | Class 9

Cell membrane offers shape and rigidity to the cell. In the case of the plant cells, besides the cell membrane, there is also an outer thick layer that is known as the cell wall. This additional layer which surrounds the cell membrane is necessary for offering the requisite protection to the plants.
The cells of the plants need protection against the variations in temperature, high wind speed, atmospheric moisture, etc. The plants are exposed to variations since they cannot move. You can easily observe the cells in the lead peel of Rhoeo, Tradescantia, or Elodea.
