Question

Quizplus · Accepted Answer

The diffusion of water across a selectively permeable (biological) membrane is known as osmosis. It is a passive process that does not require energy. It is essential for cells as it helps maintain the balance of water concentration between the cell and its surroundings. However, it can be harmful if there is an imbalance in water concentration, such as in the case of hypertonic or hypotonic solutions. Therefore, option E is incorrect. Facilitated diffusion and active transport involve the movement of molecules through specific protein channels and require energy, so options A and B are also incorrect. Option C is incorrect as osmosis is a common occurrence in cells.
