Cell Transport

3. a substance that repels or fails to mix with water
8. a process during which particles move from an area of higher concentration to an area of lower concentration
10. the solution has a higher solute concentration than the cell; there is a net movement of water molecules out of the cell causing the cell to shrink
11. a state of relatively constant internal physical and chemical conditions
14. the diffusion of water through a selectively permeable membrane
15. the process by which generic cells change into specific cells meant to do certain tasks within the body
17. the movement of a substance across a cell membrane from areas of high concentration to areas of low concentration without using cellular energy
20. a force produced by the net movement of water into or out of a cell due to differences in solute concentration
21. a protein channel that allows water to pass through a cell membrane
22. a group of tissues working together to perform a function

1. the transport of large materials by movements of the cell membrane
2. a movement of materials against a concentration difference which requires energy
4. a group of organs that work together to perform a function
5. a process in which molecules that cannot directly diffuse across a membrane pass through a special protein channel
6. an opening created in a cell membrane by a protein
7. the forcing of materials out of a cell when a vesicle or vacuole fuse with a cell membrane
9. the concentration of solutes is the same inside and outside of a cell; water molecules move equally in both directions
12. a group of similar cells that perform a particular function
13. the process of taking material into a cell by an inward folding of a cell membrane
16. the solution has a lower solute concentration than the cell; there is a net movement of water molecules into the cell causing the cell to swell
18. a site to which a signaling molecule can bind in order for a cell to respond to a chemical signal
19. the amount of a substance in a defined space
