Cell Wall | MCQs

Explanation

• Cellulose is the main component of the cell wall in plant cells, providing strength, rigidity, and shape to the cell.
• It is a complex carbohydrate made up of glucose molecules. 
• It is responsible for maintaining the cell's structure and supporting its growth.

Explanation

• Plants (made of cellulose),
• Bacteria (peptidoglycan),
• Fungi (chitin).

Explanation

The secondary cell wall, found in plant cells, is primarily composed of:

• Cellulose (a polysaccharide, the main component of plant cell walls)
• Lignin (a complex organic compound that provides strength and rigidity)

Explanation

• Fungi have cell walls made of chitin and are all heterotrophic, obtaining nutrients by decomposing organic matter or forming symbiotic relationships.
• This distinguishes them from other kingdoms, making Fungi unique in their combination of cell walls and heterotrophy.
