Diffusion and osmosis

Anmerkungen:

• Selectively permeable

Anmerkungen:

• Artificial membrane

Anmerkungen:

• Hypertonic solution (bacteria lose water)

Anmerkungen:

• Turgid / Plasmolysed (deplasmolysis)

Anmerkungen:

• high concentration to low concentration across a concentration gradient

1. Osmosis

   Anmerkungen:

   • Osmosis - water molecules across a semi-permeable membrane
   1. Solutions

      Anmerkungen:

      • Hypotonic - higher concentration of water than the other solution Hypertonic - lower concentration of water than the other solution Isotonic - Equal concentration of water to the other solution.
