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

Detailed explanation-2: -Cellulose in the cell wall is organized into strong beams called microfibrils. Cellulose microfibrils function as the backbone of the cell wall (Figure 1C). Pectin, the concrete of the plant cell wall, is more flexible than cellulose, and it allows the cell wall to extend.

Detailed explanation-3: -Plant cells have a rigid cell wall, a large central vacuole, and plastids. The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.

Detailed explanation-4: -The most characteristic component found in all plant cell walls is cellulose. It consists of a collection of -1, 4-linked glucan chains that interact with each other via hydrogen bonds to form a crystalline microfibril (Somerville, 2006).

Detailed explanation-5: -Cytoskeleton. The cytoskeleton is a network of long fibers that make up the cell’s structural framework. The cytoskeleton has several critical functions, including determining cell shape, participating in cell division, and allowing cells to move.
