Detailed explanation-1: -A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.

Detailed explanation-2: -Cell Wall-The rigid layer of material that surrounds the plant cell giving it strength and protection. Plant cell only. Cell Membrane-The outside boundary of the animal cell, the part next to the cell wall in a plant. In both cells, it controls what enters and exits the cell.

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: -The correct answer is the Cell wall. A cell wall can be defined as a rigid layer that encircles the contents of the cell. This is a semi-permeable layer that acts as a protective layer in certain types of cells.

Detailed explanation-5: -The outer covering of the cell, the cell wall is a rigid membrane that contains cellulose (a carbohydrate that is indigestible for humans). The cell wall protects the parts inside, and the cellulose molecules in the wall provide the support and rigidity needed to maintain the cell’s three-dimensional structure.
