EVERYDAY SCIENCE

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.

Detailed explanation-2: -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-3: -Cellulose is synthesized by the enzyme cellulose synthase, a membrane protein that catalyzes the direct polymerization of glucose from the substrate UDP-glucose into a cellulose product. Genes for cellulose synthases have been identified from many bacteria, Dictyostelium discoideum, and higher plants.

Detailed explanation-4: -The photosynthetic eukaryotes (so-called plant and algae) is one group with cellulose cell walls, where the cell wall is closely related to the evolution of multicellularity, terrestrialization and vascularization.
