GENERAL HISTOLOGY

Detailed explanation-1: -The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the 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: -Cell Wall Functions The cell wall can also provide protection from pathogens such as bacteria that are trying to invade the cell. The structure of the cell wall allows many small molecules to pass through it, but not larger molecules that could harm the cell.
