NEET BIOLOGY

Detailed explanation-1: -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-2: -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-3: -Complete answer: Generally, the cell wall of plants is composed of strong Cellulose but the layer of lignin forms the Secondary cell wall and this is what gives it the strength and rigidity.

Detailed explanation-4: -The plant cell wall thus has a “skeletal” role in supporting the structure of the plant as a whole, a protective role as an enclosure for each cell individually, and a transport role, helping to form channels for the movement of fluid in the plant.

Detailed explanation-5: -Plant cells have a cell wall. The cell wall provides strength and support to the plant, much like the exoskeleton of an insect or spider. Our skeletons are inside our bodies, rather than on the outside like insects or spiders. The plant cell wall is mainly made up of the carbohydrates molecules cellulose and lignin.
