Detailed explanation-1: -The cell wall is a non-living, rigid membrane that is made up of cellulose. It provides mechanical strength and support to the cell. Tonoplast is the membrane surrounding the vacuole. Chloroplast is a plastid present in plant cells that help in photosynthesis.

Detailed explanation-2: -Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth. Cellulose fibers are long, linear polymers of hundreds of glucose molecules.

Detailed explanation-3: -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-4: -Final Answer: A rigid non-living component of the cell is called th Cell wall.

Detailed explanation-5: -The biological function of cellulose in plants is to provide shape and rigidity to the cell wall. In plants, cellulose is embedded within a matrix consisting of pectin and lignin.
