Question 1: The osmotic entry of water raises the turgor pressure exerted against the ________, until it equals the osmotic pressure, creating a steady state.
Cell envelopeChloroplastCell wallBacteria

Question 2: For example, ________ and saltwater aquarium fish placed in water of a different salinity than that they are adapted to will die quickly, and in the case of saltwater fish, dramatically.
FreshwaterLakeEarthWater resources

Question 3: When a cell is submerged in ________, the water molecules pass through the cell membrane from an area of low solute concentration (outside the cell) to one of high solute concentration (inside the cell), this is called osmosis.
WaterWater resourcesOxygenEarth

Question 4: As mentioned before, osmosis may be opposed by increasing the ________ in the region of high solute concentration with respect to that in the low solute concentration region.

Question 5: Forward osmosis is an area of ongoing research, focusing on applications in ________, water purification, water treatment, food processing, etc.
Multiple-effect distillationMulti-stage flash distillationElectrodialysis reversalDesalination

Question 6: Osmosis may occur when there is a partially-permeable membrane, such as a ________.
Cell (biology)Vesicle (biology)Cell membraneCell nucleus

Question 7: Since a solution possesses more entropy than pure solvent, the ________ states that solvent molecules will flow into the solution until the entropy of the combined system is maximized.
History of thermodynamicsExergySecond law of thermodynamicsGibbs free energy

Question 8: In general, these membranes are impermeable to organic solutes with large molecules, such as ________, while permeable to water and small, uncharged solutes.
PolysaccharideCarbohydrateStarchCellulose

Question 9: (This means the cell has become plasmolysed - the ________ has completely left the cell wall due to lack of water pressure on it; the opposite of turgid.)
Vesicle (biology)Cell nucleusCell (biology)Cell membrane

Question 10: Osmosis provides the primary means by which ________ is transported into and out of cells.
