How does water move across a cell membrane?
Explanation
Water moves across a cell membrane through osmosis. Osmosis is the process by which water molecules diffuse through a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this case, water moves from an area of lower solute concentration (hypotonic solution) to an area of higher solute concentration (hypertonic solution) until equilibrium is reached. This movement of water is crucial for maintaining the balance of water and solutes inside and outside the cell.Rate this question:
- 7.
How do particles move across a cell membrane?
Explanation
Particles move across a cell membrane through diffusion. Diffusion is the process by which particles move from an area of higher concentration to an area of lower concentration. This movement occurs due to the random motion of particles. In the case of a cell membrane, particles such as ions, gases, and small molecules can pass through the lipid bilayer or protein channels via diffusion. This allows for the exchange of essential substances, such as oxygen and nutrients, between the cell and its environment.Rate this question:
