Answer 1

Answer:

D. The cell wall is mainly composed of cellulose

• The cell wall is a rigid layer outside the cell membrane that provides structural support, protection, and maintains the cell's shape.

• In plant cells, the cell wall is indeed mainly composed of cellulose, a complex carbohydrate made up of glucose molecules.

• Cellulose provides strength, rigidity, and elasticity to the cell wall, allowing plants to grow and maintain their shape.
