Question

ex 5 ryk a
transport across the plasma membrane
match the definition with the term
a. to shrink or shrivel
b. water moving through selectively permeable membrane
c. substance dissolved in a solution
d. to burst a red blood cell
e. difference b/w solute concentrations across a membrane
f. same solute concentration on both sides of membrane
g. lower concentration of solutes outside the cell than in cytosol of cell
h. a fluid that contains dissolved substances
i. higher concentration of solutes outside the cell than in cytosol of cell
j. random movement of particles from their greater concentration to their lesser concentration

1. concentration gradient
2. crenate
3. diffusion
4. hemolysis
5. hypertonic solution
6. hypotonic solution
7. isotonic solution
8. osmosis

9 solute

1. solvent

Explanation:

1. A concentration gradient is the difference between solute concentrations across a membrane, so e matches 1.
2. To crenate means to shrink or shrivel, so a matches 2.
3. Diffusion is the random movement of particles from their greater concentration to their lesser concentration, so j matches 3.
4. Hemolysis is to burst a red - blood cell, so d matches 4.
5. A hypertonic solution has a higher concentration of solutes outside the cell than in the cytosol of the cell, so i matches 5.
6. A hypotonic solution has a lower concentration of solutes outside the cell than in the cytosol of the cell, so g matches 6.
7. An isotonic solution has the same solute concentration on both sides of the membrane, so f matches 7.
8. Osmosis is water moving through a selectively permeable membrane, so b matches 8.
9. A solute is a substance dissolved in a solution, so c matches 9.
10. A solvent is a fluid that contains dissolved substances, so h matches 10.

Answer:

1. e. difference b/w solute concentrations across a membrane
2. a. to shrink or shrivel
3. j. random movement of particles from their greater concentration to their lesser concentration
4. d. to burst a red blood cell
5. i. higher concentration of solutes outside the cell than in cytosol of cell
6. g. lower concentration of solutes outside the cell than in cytosol of cell
7. f. same solute concentration on both sides of membrane
8. b. water moving through selectively permeable membrane
9. c. substance dissolved in a solution
10. h. a fluid that contains dissolved substances
