Water Potential

Question 1

Solvation

Answer 1

the interaction of a solvent with dissolved molecules or ions

Question 2

Hypertonic

Answer 2

a solution that has a higher concentration of dissolved substances (solutes) compared to another solution, typically a cell’s internal fluid

water flows out of the cell

Question 3

Hypotonic

Answer 3

a solution that contains a lower concentration of solutes compared to another solution or cell

water flows into the cell

Question 4

Isotonic

Answer 4

when the external solution has the same concentration as the internal solution

no net flow of water

Question 5

Dynamic Equilibrium

Answer 5

both forward and reverse reactions occurring simultaneously, at the same rate, while the amount of reactants and products remains unchanged

Question 6

Osmotic Concentration

Answer 6

measures the total number of solute particles dissolved in a solution, specifically the number of osmolal units of solute per liter of solution

1 mole of solute dissolved in 1L of water is 1 Osm

Question 7

Contractile Vacuole

Answer 7

a small vesicle in the cytoplasm of many freshwater protists that expels excess water

Question 8

Turgor Pressure

Answer 8

hydrostatic pressure in a cell that pushes the plasma membrane against the cell wall

Question 9

Turgid

Answer 9

condition when the vacuole of the cell is full of water and pushes the cell membrane against the cell wall

(swollen and hard)

Question 10

Flaccid

Answer 10

plant cell that has become soft and less rigid than normal because it was placed in a hypertonic solution

Question 11

Plasmolysis

Answer 11

the process where a plant cell loses water in a hypertonic solution, causing the cytoplasm and plasma membrane to shrink away from the cell wall

Question 12

Water Potential

Answer 12

the potential energy of water per unit volume. Uses the units of pressure (kPa)

quantifies the tendency of water to move from one area to another

due to osmosis
