Question
Cell wall in a plant cell is made of ___________.
- Glucose
- Cellulose
- Peptidoglycan
- Fat
Hint:
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.
The correct answer is: Cellulose
The cell wall consists of a network of cellulose molecules and cross-linking glycans embedded in an extremely cross-linked matrix of cellulose polysaccharides. The cell wall surrounds the cytomembrane of plant cells and provides tensile strength and protection against mechanical and diffusion stress.
