Cell wall does what?

Cell wall does what?

• A. Stores energy
• B. Reads genetic code
• C. Supports and protects the cell
• D. Carries out photosynthesis

Answer: (C)

The cell wall’s main role is to provide structure and protection for the cell. It’s a rigid outer layer found in plants, fungi, and some bacteria, and it helps give the cell a defined shape while supporting it against mechanical stress. It also helps prevent the cell from bursting when water pressure is high. Because it’s porous, it lets water and small molecules pass through, but it isn’t involved in storing energy, reading genetic code, or carrying out photosynthesis—these functions occur in other parts of the cell (energy storage in organelles like mitochondria, genetic information handled in the nucleus and by ribosomes, photosynthesis in chloroplasts). So the cell wall is best described as providing support and protection.
