1. As promised, here are the answers to the VOCABULARY REVIEW.
HI KIDS!
As promised, here are the answers to the VOCABULARY REVIEW.
Make sure you notice that this Power Point actually includes 47 terms, rather than just the 40 that are on the Study Guide sheet.
Good luck studying for Monday’s quiz!

2. 1. Double layer of phospholipids that make a cell membrane: PHOSPHOLIPID BILAYER   2. Another term for cell membrane: PLASMA MEMBRANE (PHOSPHOLIPID BILAYER)   3. Term that describes being chemically repelled by water: HYDROPHOBIC   4. Another word for fat: LIPID   5. What the two hydrophobic tails of a phospholipid are composed of: FATTY ACIDS

3. 6. Types of proteins that help move substances into and out of a cell: TRANSPORT   7. Passive type of movement of particles in which they randomly move from an area of high concentration to an area of low concentration: DIFFUSION   8. PO43- : PHOSPHATE   9. Term that describes being chemically attracted to water: HYDROPHILIC   10. The watery substance inside a cell: CYTOPLASM

4. 11. Type of diffusion allowed by transport proteins that provide a pathway for molecules that have difficulty crossing the plasma membrane: FACILITATED DIFFUSION   12. Water and sugar molecules both have trouble crossing a plasma membrane because they are both: POLAR   13. Types of molecular movements that do not require an input of energy: PASSIVE   14. Shrinking of a cell due to a loss of water: PLASMOLYSIS   15. A cloud of smoke dispersing into the surrounding air demonstrates: DIFFUSION

5. 16. When a cell uses its membrane to engulf surrounding particles, and forms vesicles in the process: ENDOCYTOSIS   17. A carrot becoming rubbery by being saturated with salt water demonstrates: PLASMOLYSIS   18. Type of solution that has a higher concentration of solute than another solution: HYPERTONIC   19. Word that describes a cell membrane’s tendency to allow only certain materials into and out of the cell: SELECTIVELY PERMEABLE / SEMIPERMEABLE   20. Tiny packages of substances within a cell; like little bubbles produced by engulfing movements of the cell membrane: VESICLES  

6. 21. Term that describes a solution that has a lower concentration of solute than another solution: HYPOTONIC   22. Salt water would be this compared to distilled water: HYPERTONIC   23. Material used in a science lab to simulate a plasma membrane: DIALYSIS TUBING
24. Process in which materials are ejected from a cell using vesicles and the plasma membrane:
EXOCYTOSIS
25. The condition reached once concentrations balance on both the inside and outside of a cell:
EQUILIBRIUM

7. 26. The diffusion of water into (or out of) a cell across a semipermeable membrane: OSMOSIS   27. Endocytosis on a grand scale: PHAGOCYTOSIS   28. Food coloring dropped into a beaker of water demonstrates this process: DIFFUSION   29. “Starch piggies” basking in iodine simulate this process: OSMOSIS   30. Term that describes when concentrations of a solution are equal: ISOTONIC (NOT EQUILIBRIUM IN THIS CONTEXT)

8. 31. When a cell needs to exert energy to move molecules or ions across a membrane: ACTIVE TRANSPORT   32. If you were to drink salt water, your cells would undergo this: PLASMOLYSIS   33. When an Amoeba uses its pseudopodia to engulf its prey: PHAGOCYTOSIS   34. In a solution, the liquid that does the dissolving is the: SOLVENT   35. In a solution, the substances that are dissolved are the: SOLUTES

9. 36. When a macrophage engulfs bacteria: PHAGOCYTOSIS 37
36. When a macrophage engulfs bacteria: PHAGOCYTOSIS   37. Compared to cytoplasm, distilled water is: HYPOTONIC   38. The combination of a solute dissolved in a solvent is a: SOLUTION   39. Red blood cells swell up when exposed to this kind of solution: HYPOTONIC   40. A simple sugar that could enter a cell via facilitated diffusion: GLUCOSE

10. 41. Because glycoproteins have a carbohydrate “antenna”, which can be used to identify a cell, they can be called this type of protein: MARKER 42. This type of transmembrane protein can be the site where certain chemicals bond with the surface of a cell and produce a biochemical reaction: RECEPTOR 43. This transmembrane protein is a gateway that allows facilitated diffusion: CHANNEL

11. 44. Liquid on the outside of a cell (on the opposite side of the plasma membrane as the cytoplasm): EXTRACELLULAR FLUID 45. A special type of protein that specializes in the transmission of water through the hydrophobic zone of the plasma membrane: AQUAPORIN Endocytosis of a liquid (“cell drinking”) PINOCYTOSIS
47. General term for any molecule that binds to a receptor site on a receptor protein:
LIGAND
