Which structure is responsible for maintaining homeostasis in a cell?

• A. Cell wall
• B. Cell membrane
• C. Nucleus
• D. Vacuole

Answer: (B)

The cell membrane plays a crucial role in maintaining homeostasis within a cell. It acts as a selective barrier, regulating the movement of substances in and out of the cell. This selective permeability ensures that essential ions and nutrients can enter the cell while waste products are efficiently removed. Additionally, the cell membrane contains various proteins and receptors that allow the cell to respond to changes in the environment. Through processes such as osmosis and diffusion, the membrane helps to maintain the right balance of water, ions, and other molecules, which is vital for the cell's overall function and health. Therefore, its primary function in facilitating communication and controlling internal conditions makes it essential for homeostasis.
