LIFE SCIENCE

Detailed explanation-1: -A thick, fairly rigid layer formed around individual cells of bacteria, Archaea, fungi, plants, and algae, the cell wall is external to the cell membrane and helps the cell maintain its shape and avoid damage.

Detailed explanation-2: -The cell wall of fungus is made up of fungal cellulose and cell wall of bacteria is made up of peptidoglycans. Fungal cellulose or chitin microfibrils are made up of bundles of unbranched chains of -1, 4 acetyl glucosamine residues. Peptidoglycans are the structural elements of almost all the bacterial cell walls.

Detailed explanation-3: -Plant cells are surrounded by a tough extracellular matrix in the form of a cell wall, which is responsible for many of the unique features of a plant’s life style.
