Detailed explanation-1: -The cell wall is the outermost covering of plant cells. The cell wall is present only in plants and in some fungi, bacteria and algae. It is present outside the cell membrane and is tough, flexible and sometimes rigid in its texture.

Detailed explanation-2: -The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection.

Detailed explanation-3: -The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.

Detailed explanation-4: -Cell Wall-Each bacterium is enclosed by a rigid cell wall composed of peptidoglycan, a protein-sugar (polysaccharide) molecule. The wall gives the cell its shape and surrounds the cytoplasmic membrane, protecting it from the environment.

Detailed explanation-5: -Cell Wall: Protective Coat in Plant Cells The cell wall is rigid and is composed of cellulose fibre, polysaccharides, and proteins.
