Annotations:

• Selectively permeable

Annotations:

• Artificial membrane

Annotations:

• Hypertonic solution (bacteria lose water)

Annotations:

• Turgid / Plasmolysed (deplasmolysis)

Annotations:

1. Osmosis

   Annotations:

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

      Annotations:

      • 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.
