IB Biology B3.2.7 Water transport in plants
Practise explaining water movement from soil to leaves through roots, xylem and transpiration, including conditions where humidity changes the route.
How this is tested
- explain how evaporation from leaves creates tension that pulls water through xylem
- link root ion uptake and osmosis to water entry when transpiration is reduced
- predict water or dissolved substance movement from soil to leaves in plant scenarios
