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: -Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth.
Detailed explanation-3: -Cellulose is the primary structural component responsible for much of the mechanical strength of the cell wall. The distribution and orientation of cellulose microfibrils within the cell wall contribute to the control of cell growth.
Detailed explanation-4: -Organisms that possess cell wall in their cellular structure include-bacteria, fungi and plants. Bacterial cell walls are made up of peptidoglycan, plant cell walls are made up of cellulose and the fungal cell walls are made up of chitin.
Detailed explanation-5: -Unlike those of plants and algae, fungal cell walls lack cellulose entirely and contain chitin.
