Osmosis is the diffusion of water through a:
If a potato cylinder gains mass after being left in a solution, what is the best explanation?
In osmosis, water moves from:
Osmosis in Action
A dilute solution has a high concentration of water; a concentrated solution has a low concentration.
Plant cells rely on osmosis to stay turgid and support the plant structure.
Always mention "partially permeable membrane" to secure full marks for the definition of osmosis.
