ANATOMY

Detailed explanation-1: -The cellulose molecules provide tensile strength to the primary cell wall.

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: -Cell wall is present outside the cell membrane. It has the function of giving shape and rigidity to the cell. Cell wall is present only in plants hence it is the characteristic feature that distinguishes between plant and animal cells.

Detailed explanation-4: -The strongest component of the cell wall is a carbohydrate called as cellulose, a polymer of glucose. When the additional layer of lignin is added to the primary cell wall a secondary cell wall is formed. Secondary cell wall increases the rigidity and strength of the cell.

Detailed explanation-5: -The rigid exterior around the cells is necessary to allow the plants to grow upright. Plant cells have a cell wall, as well as a cell membrane. The cell wall provides structural support and protection. This gives the plant cells their distinct rectangular or pentagonal shape.
