IB Biology SL 2.4.6 Osmosis in plant cells Question Bank

a. osmosis is water moving through a partially/semi permeable membrane/cell membrane/aquaporins;

b. osmosis is a form of simple diffusion

OR

water travels down the (water) concentration gradient

OR

osmosis is passive;

c. the solute concentration determines the direction of net movement of water;

d. plant cells in hypotonic solutions will take in water;

e. they will swell/are turgid/develop turgor pressure (in hypotonic solutions);

f. cell wall prevents the plant cells from bursting due to water pressure (in hypotonic solutions);

g. plant cells in hypertonic solutions will lose water;

h. they will shrink/get smaller/flaccid (in hypertonic solutions);

i. the cell membrane will pull away from the cell wall/plasmolysis (in hypertonic solutions);

j. isotonic solutions are the same concentration as inside the plant cells/cytoplasm/cell sap;

k. plant cells will have no net change (in isotonic solutions)/water moves equally in and out of the cell/dynamic equilibrium;
