Across
- 4. A lipid in the cell membrane that keeps it fluid.
- 6. Water channel protein that allow water to pass directly through them and into/out of the cell.
- 7. When molecules move from low to high concentration using energy.
- 12. When a solution has a higher solute concentration compared to the cell. This will cause water to rush out of the cell.
- 13. When the solute concentration in the cell and out of the cell is equal, causing water to constantly move in and out of the cell to maintain equality.
- 15. Process by which a cell releases a large amount of material through the membrane.
- 16. Process of taking material into the cell by means of inward folding of the cell membrane.
- 18. The movement of water molecules that affect a cells health (i.e., shrink, swell)
- 19. A property of cell membranes that allows certain substances to pass through, but others cannot.
Down
- 1. When a solution has a lower solute concentration compared to the cell. This will cause water to rush into the cell.
- 2. The movement of particles from high to low concentration using a protein channel. Molecules that move by this method of transport are larger and have a charge.
- 3. A stable internal environment maintained by an organism.
- 5. When particles/molecules are equal on both sides of the cell membrane.
- 8. Makes up the cell membrane and has a hydrophilic head and hydrophobic tails.
- 9. Model of the cell membrane that explains how the cell membrane is fluid and can change shape.
- 10. A protein channel that carries ions (charged molecules) across the cell membrane.
- 11. The process by which particles move from an area of high concentration to low concentration.
- 14. The outer boundary of the cell that controls what goes in and out. It is made of phospholipid molecules.
- 17. Water molecules moving from high to low concentration across a membrane.
