What is one function of the cell wall in plant cells?

• A. To store genetic information
• B. To provide structural support
• C. To assist in movement
• D. To facilitate energy production

Answer: (B)

The cell wall in plant cells primarily serves the function of providing structural support. It is a rigid layer made primarily of cellulose, which gives the plant cell its shape and strength. This structural integrity is essential for plants, as it helps them maintain their upright position and protects them from physical damage and environmental stresses. In addition to support, the cell wall also plays a role in regulating the passage of substances in and out of the cell, but its main purpose is to ensure that the plant holds its shape and can resist external pressures. Other components, such as the cell membrane, are more involved in genetic information storage and energy production in the cell. Therefore, the option highlighting structural support accurately reflects a key role of the cell wall in plant cells.
