D2.3 Water Potential

Question 1

Solvation

Answer 1

Solvation is the interaction of a solvent with a dissolved solute

Refers to how the network of hydrogen bonds are built around the solute

Question 2

three steps of solvation

Answer 2

the particles of a solute separate from each other

the water particles separate from each others

the separated solute and water particles combine to make a solution

Question 3

problems animal cells face in hypertonic environments

Answer 3

Hypertonic environment: net water movement out of the animal cell and causes the cell to shrink and result in crenation

Question 4

problems animal cells face in hypotonic environments

Answer 4

Hypotonic environment: net water movement enter the animal cell and causes the cell to swell and burst

Question 5

Turgor pressure

Answer 5

the hydrostatic pressure within the cell that pushes the plasma membrane against the cell wall

Question 6

Plasmolysis

Answer 6

the contraction of the cytoplasm (and central vacuole) due to water loss within the plant cell

Question 7

what is crenation

Answer 7

extreme shrinkage where the cell becomes crinkled

Question 8

Intravenous fluid (IV fluid)

Answer 8

this fluid is injected into a patient’s veins through an IV tube to prevent the patient from dehydration and maintain the level of electrolytes in the patient’s body normal during medical treatments

Organs need to be immersed in isotonic solutions during the transport and storage before organ transport surgeries can be done to keep the cells alive and not dehydrate or lyse
