Osmosis refers to the movement of ___ across a semi-permeable membrane from an area of high concentration to an area of low concentration.
The cell membrane is responsible for controlling what enters and leaves the cell.
In a hypertonic solution, water moves into the cell causing it to swell.
What function does the cell membrane serve in a cell?
What occurs to a red blood cell in a hypotonic solution?
How does osmosis differ from diffusion?
What role does the cell membrane play in cell function?
What happens to a red blood cell in a hypotonic solution?
