LIFE SCIENCE

Detailed explanation-1: -It provides the cell with both structural support and protection, and also acts as a filtering mechanism. Cell walls are absent in many eukaryotes, including animals, but are present in some other ones like fungi, algae and plants, and in most prokaryotes (except mollicute bacteria).

Detailed explanation-2: -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-3: -Cellulose is a natural polymer made of smaller sugar units. It is present in cell walls of plant cells. It gives remarkable strength to the cell. It also helps in the absorption of water thus, preventing desiccation of cell.

Detailed explanation-4: -Gives the cell a definite shape and structure. Provides structural support. Protection against infection and mechanical stress. Separates interior of the cell from the outer environment. It enables transport of substances and information from the cell insides to the exterior and vice versa. More items
