movement of specific molecules across cell membranes through protein channels having a higher osmotic pressure than a comparison solution having a lower osmotic pressure than a comparison solution diffusion of water through a selectively permeable membrane transport of a substance across a cell membrane by diffusion allowing to pass or diffuse through when a cell is in a hypertonic environment, the cell will lose water to its surroundings, shrink, and its plasma membrane will pull away from the wall  

1. facilitated diffusion

movement of specific molecules across cell membranes through protein channels

2. hypertonic

having a higher osmotic pressure than a comparison solution

3. hypotonic

having a lower osmotic pressure than a comparison solution

4. osmosis

diffusion of water through a selectively permeable membrane

5. passive transport

transport of a substance across a cell membrane by diffusion

6. permeable

allowing to pass or diffuse through

7. plasmolysis

when a cell is in a hypertonic environment, the cell will lose water to its surroundings, shrink, and its plasma membrane will pull away from the wall
