Osmosis Flashcards
Define osmosis
The net movement of water molecules from a region of high water potential to a region of low water potential through a selectively permeable membrane
What is water potential
The pressure created by water molecules
How do the water molecules move region during osmosis and how is it a passive process
Selectively permeable membrane allows passage
Random motion due to internal kinetic energy causes net movement
What is the water potential of pure water
0
What can happen to a cell during osmosis if the cell has a lower water potential
Cell can swell and burst
What can happen to the cell during osmosis if the internal water potential is Higher than it’s environment
The cell can shrink
What is the condition of a plant cell when it shrinks due to osmosis
Plasmolysed
What is the condition of a plant cell when it remains the same shape during osmosis
Incipient plasmolysis
What is the condition of a plant cell when it grows in size
Turgid
