Definitions:
1. Movement of material across the cell membrane with energy
2. The environment outside of the cell has a lower concentration of dissolved material than the inside of the cell. This causes the cell to swell, and it may even burst.
3. A difference in the concentration of a substance across a distance
4. Movement of material across the cell membrane without energy
5. The environment outside of the cell has more dissolved material than inside of the cell. If a cell is placed in a this type of solution, water will leave the cell. This can cause a cell to shrink and shrivel (crenation).
6. The movement of particles from regions of higher density to lower density regions
7. Diffusion of water across a selectively permeable membrane
8. Concentration of a substance is the same throughout a space
9. A solution in which the amount of dissolved material is equal both inside and outside of the cell. Water still flows in both directions, but an equal amount enters and leaves the cell.
10. The movement of large molecules through a membrane protein channel along the concentration gradient.
