NEET BIOLOGY

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

Detailed explanation-2: -Silicon is a beneficial plant nutrient that can increase plant strength and improve a crop’s ability to fight environmental oxidative stress. Silicon is an element that, like calcium, potassium, or zinc, is used by the plant to complete physiological processes.

Detailed explanation-3: -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.

Detailed explanation-4: -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. The cell is a necessary part of the plant cell as it protects and provides the cells the structural support.

Detailed explanation-5: -Cellulose fibers, structural proteins, and other polysaccharides help to maintain the shape and form of the cell. Additional functions of the cell wall include: Support: The cell wall provides mechanical strength and support.
