A. A chloride ion moves across the plasma membrane from a higher to lower concentration inside the cell.
Explanation:
Diffusion is the movement of particles from a region of higher concentration to that of lower concentration. Sometimes diffusion may require energy input to drive it.
- In facilitated diffusion, the concentration gradient creates the drive that fosters the diffusion.
- A membrane allows for the movement of tiny particles of matter across two regions.
- When the concentration in a region is above that of another, particles will move from the area having high concentration to that with a lower concentration till they both attain uniform concentration.
- This is known as facilitated diffusion.
