What is the sequence of events in the translocation of sucrose?
active loading of sucrose into sieve elements at the source, increased hydrostatic pressure, mass flow, unloading at the sink
2 )
hydrolysis of storage compounds in sinks, lowered water potential, unloading of sucrose from sieve elements, mass flow from the source
3 )
lowered pressure in sieve elements at the source, movement of sucrose down the pressure gradient, mass flow down a diffusion gradient to the sink
4 )
mass flow of dissolved sucrose into the sieve element at the source, lowered hydrostatic pressure, diffusion of sucrose to sink, active unloading
