Question

Describe evidence for role of active transport in moving water from root endodermis into xylem.

Accepted Answer

Evidence for role of active transport in root pressure:Poisons - affect mitochondria, prevent ATP production - root cells have no energy supply - root pressure disappearsRoot pressure increases with rise in temp - suggests chemical reations involvedIf levels of oxygen/respiratory substrates fall, root pressure falls - it relies on energy
