CAIE IGCSE Biology 3.2.6 Plants are supported by the pressure
Practise explaining how water pressure inside plant cells supports tissues by pressing outwards on rigid cell walls.
How this is tested
- select the statement that links plant support to water pressure pressing on cell walls
- explain turgor pressure in cells with walls, including why rigid walls resist expansion
- link ion uptake in roots to maintaining a water potential gradient for water entry
