level questions: Osmosis

QuestionAnswer
Define osmosisthe net movement of water molecules from a high water potential to a lower water potential down a water potential gradient through a selectively permeable membrane
What is the water potential of pure waterzero
What does a more negative water potential meanthe stronger the concentration of solutes in the solution
Define hypertonicsolution that has low water potential, therefore there's a net movement of water out of the cell into the solution.
What happens if an animal cell is placed in a hypertonic solutionit will shrink
What happens if an plant cell is placed in a hypertonic solutionit will become flaccid
Define plasmolysisWhen the cytoplasm and plasma membrane pull away from the cell wall.
Define isotonicwhen two solution have the same water potential, therefore there's no net movement of water
Define hypotonicsolution has a high water potential, therefore net movement of water is into the cell
What happens if an plant cell is placed in a hypotonic solutionthe vacuole will swell and the contents of the cell will push against the cell wall, causing cell to be turgid
What happens if an animal cell is placed in a hypotonic solutionit will well and eventually burst
