IB Biology HL B2.1.5 Osmosis & aquaporins
Practise explaining osmosis and aquaporins using water movement, osmolarity and experimental results from frog egg cell volume changes.
How this is tested
- explain water movement across selectively permeable membranes during osmosis
- interpret frog egg cell volume changes with and without aquaporin mRNA
- distinguish osmolarity from water movement direction in cell examples
