Answer:
In plant cells, there is a thick, strong and rigid cell wall which lies outside the plasma membrane.
And is secreted by the cell itself for the protection of its plasma membrane and cytoplasm. The cell itself wall determine the shape of an plant cell and prevent dessication of cell. It is thick layer of cellulose And non living in nature.
• It provides mechanical strengh to the cell
• It control the size and shape of the cell
• It protect the plant cells against variations in temperature high wind speed, atmospheric moisture, etc.

Answer:
Cell wall
In plant cells, there is a thick, strong and rigid cell wall which lies outside the plasma membrane.
It is freely permeable .
And is secreted by the cell itself for the protection of its plasma membrane and cytoplasm. The cell itself wall determine the shape of an plant cell and prevent dessication of cell. It is thick layer of cellulose And non living in nature.
