Detailed explanation-1: -Cell wall is a rigid covering present outside the plant cell which is composed of a complex structural substance called cellulose.

Detailed explanation-2: -The Cell Wall A cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell. The cell wall contains not only cellulose and protein, but other polysaccharides a s well . The cell wall provides structural support and protection.

Detailed explanation-3: -The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength shape, rigidity and structure to filter molecules that pass in and out of the cell. It is made up of cellulose.

Detailed explanation-4: -The cell wall This structure maintains the cell’s shape, protects the cell interior, and prevents the cell from bursting when it takes up water. The cell wall of most bacteria contains peptidoglycan, a polymer of linked sugars and polypeptides.

Detailed explanation-5: -Cells of bacteria, fungi, algae, and higher plants are surrounded by rigid cell walls, which are an integral part of the cell. Although not encased in cell walls, animal cells in tissues are closely associated with an extracellular matrix composed of proteins and polysaccharides.
