D2.3 Water potential SL

Question 1

Solvent Properties of Water

Answer 1

Water dissolves many substances due to its polarity, forming hydration shells

Question 2

Water Movement

Answer 2

Water moves from less to more concentrated solutions via osmosis

Question 3

Water’s net movement across a membrane from lower to higher solute concentration

Answer 3

Osmosis

Question 4

Lower solute concentration than cell cytoplasm, causing cell swelling

Answer 4

Hypotonic Solution

Question 5

Hypertonic Solution

Answer 5

Higher solute concentration than cell cytoplasm, leading to cell shrinkage

Question 6

Isotonic Solution

Answer 6

Equal solute concentration to cell cytoplasm, with balanced water movement

Question 7

Water Potential

Answer 7

Determines water movement into/out of cells

Question 8

Swells and may burst due to water influx

Answer 8

Animal Cell in Hypotonic Solution

Question 9

Undergoes plasmolysis due to water loss

Answer 9

Plant Cell in Hypertonic Solution

Question 10

Dynamic Equilibrium

Answer 10
