Biology 2.1.5 Osmosis and water potential
Cards in this deck (10)
- 1Define osmosisThe movement of water molecules across a partially permeable membrane down the water potential gradient, from an area of higher water potential to an area of lower water potential
- 2Across what membrane does osmosis occur?Partially permeable
- 3What is the water potential of pure water?0
- 4Define water potentialThe tendency for water to leave a solution
- 5What happens to the water potential when a solute is added to a solution?The water potential decreases
- 6Are values of water potential always positive or negative?Negative
- 7What is an isotonic solution?When the two solutions have the same concentration
- 8What happens to a cell in a isotonic solution?Nothing
- 9What is a hypotonic solution?Where the concentration of the solution is less than that of the cell in it
- 10What is a hypertonic solution?A hypertonic solution has a greater concentration of solutes than the cell in it
