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

hydrolysis of storage compounds in sinks, lowered water potential, unloading of sucrose from sieve elements, mass flow from the source

lowered pressure in sieve elements at the source, movement of sucrose down the pressure gradient, mass flow down a diffusion gradient to the sink

mass flow of dissolved sucrose into the sieve elements at the source, lowered hydrostatic pressure, diffusion of sucrose to sink, active unloading
