Detailed explanation-1: -The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited.

Detailed explanation-2: -The plant cell wall is made up of cellulose which is a complex substance and provides structural strength to the plants.

Detailed explanation-3: -Hydrilla, Mango tree, and cactus are plants hence their cell wall is made up of cellulose. The cell wall of Bacteria is made of polysaccharide called Peptidoglycan.

Detailed explanation-4: -Final answer: Cell wall of bacteria is not made up of cellulose.

Detailed explanation-5: -Cellulose is the most abundant biopolymer, as it comprises the major structural component of the cell walls of lower and higher plants. We find high cellulose contents in stalks and stems and in other woody parts of plants.
