Water moves through leaf tissues via different pathways because of: • differences in water potential • the pull passed on by cohesive forces between water molecules. The diagram illustrates three pathways along which water may move. Which row correctly shows why water moves across leaf tissues by the different pathways?
- ADifferences in water potential: route 1; pull transmitted by cohesive forces: routes 2 and 3
- BDifferences in water potential: routes 1 and 3; pull transmitted by cohesive forces: route 2
- CDifferences in water potential: route 2; pull transmitted by cohesive forces: routes 1 and 3
- DDifferences in water potential: routes 2 and 3; pull transmitted by cohesive forces: route 1
