1. "Hypo" means " than".
2. transport requires the use of cell energy to move materials through the cell membrane against the concentration gradient.
3. is a specific term referring to the movement of small particles or liquids into the cell.
4. diffusion moves substances passively through the membrane from high concentrations to low concentrations using carrier proteins.
5. is a specific term referring to the movement of large particles or solids into the cell.
6. solutions have equal concentrations of solutes inside and outside the cell.
7. solutions have lower concentrations of solutes outside the cell.
8. solutions have higher concentrations of solutes outside the cell.
9. transport allows substances to enter the cell without any energy being used from the cell.
10. A cell that is 70 percent water is placed into a 30 percent sugar water solution, what will
happen to the cell? Water will move of the cell .
11. A concentration refers to the difference between the high and low concentrations.
12. A cell that is 60 percent water is placed into a 30 percent sugar solution in water. What will happen to the cell? Water will move the cell.
13. A general term that refers to the bulk transport of large objects into the cell is .
14. Animal cells have no cell walls. When placed in hypotonic solutions animal cells may or burst.
15. Because of osmosis, plant cells build up water pressure inside. This pressure is called .
16. Bulk movement of materials out of the cell is referred to as .
17. Cell membranes are selectively , which means that they allow only certain substances to pass through.
18. Diffusion rates may be affected by: concentration, temperature, and .
19. Distilled water has no solutes and is therefore to all cells.
20. Glucose enters cells through the process of diffusion.
21. Hypertonic solutions cause water to flow of a cell. (like putting salt on a snail)
22. Hypotonic solutions cause water to flow the cell.
23. If a cell that is 80 percent water is placed into a 30 percent sugar in water solution, what will happen to the cell? Water will move the cell.
24. If a cell that is 80 percent water is placed into a distilled water solution, what will happen to the cell? Water will move the cell.
25. and diffusion are examples of passive transport which take place without cell energy.
26. Osmosis depends on the concentration gradient on each side of the membrane which is
determined by the concentration of dissolved in the water.
27. Some cells may pump out excess water through special organelles called vacuoles.
28. Special protein molecules called molecules move some larger molecules through the membrane.
29. The bursting of cells due to osmosis is referred to as .
30. The cell membrane is composed of a double layer of with some proteins embedded in and through it.
31. The current model of membrane structure is called the Fluid Model.
32. The diffusion of water through a selectively permeable membrane is termed .
33. The prefix "hyper" means " than".
34. The prefix "iso" means "".
35. The random motion of molecules (when first observed) was referred to as motion.
36. The random motion of molecules that occurs from a region of higher concentration to a region of lower concentration is called .
37. The shrinking of cells due to osmosis is referred to as .
38. Water flows in and out of cells until it reaches (equal concentrations). Then it
continues to flow both directions in equal amounts.
