What is the purpose of the cell wall in plant cells?

• A. To facilitate cell division
• B. To protect against pathogens
• C. To provide structure and support
• D. To store genetic material

Answer: (C)

The purpose of the cell wall in plant cells is to provide structure and support. The cell wall is a rigid outer layer made primarily of cellulose that surrounds the cell membrane. This structure is crucial for maintaining the shape of the plant cell and allowing it to withstand various environmental pressures. It helps prevent the cell from bursting when it takes in water through osmosis by providing turgor pressure, which is essential for maintaining plant rigidity and upright growth. Additionally, the cell wall acts as a barrier that helps to protect the plant cell from mechanical damage and pathogens, although its primary role is in support and structure.
