The
Plant cells have cell walls, constructed outside the cell membrane and composed of cellulose, hemicelluloses, and pectin. Their composition contrasts with the cell walls of fungi, which are made of chitin, of bacteria, which are made of peptidoglycan and of archaea, which are made of pseudopeptidoglycan

Overview of Plant Cell Wall Composition
The plant cell wall is a crucial structure that provides support, protection, and shape to plant cells. Understanding its composition is essential for grasping plant biology.
Main Component: Cellulose
- Cellulose is the primary structural component of the plant cell wall.
- It is a polysaccharide made up of long chains of glucose molecules.
- Cellulose fibers are arranged in a way that provides strength and rigidity to the cell wall.
Function of Cellulose in the Cell Wall
- Structural Support: The rigidity of the cellulose fibers helps maintain the shape of the plant cell.
- Protection: It acts as a barrier against mechanical stress and pathogens.
- Water Regulation: The cell wall helps regulate water uptake and loss, contributing to overall plant health.
Comparison with Other Carbohydrates
- Starch: Primarily a storage form of energy in plants, not a structural component.
- Glycogen: A storage carbohydrate in animals, not found in plant cells.
- Inulin: A storage carbohydrate found in some plants but not a component of the cell wall.
Conclusion
The correct answer to the question about the composition of the plant cell wall is option 'A' - Cellulose. Its unique properties and structure are integral to the functionality and integrity of plant cells, distinguishing it from other carbohydrates like starch, glycogen, and inulin.
