What is the order of events during the translocation of sucrose?
- Aactive loading of sucrose into sieve elements at the source, increased hydrostatic pressure, mass flow, unloading at the sink
- Bhydrolysis of storage compounds in sinks, lowered water potential, unloading of sucrose from sieve elements, mass flow from the source
- Clowered pressure in sieve elements at the source, movement of sucrose down the pressure gradient, mass flow down a diffusion gradient to the sink
- Dmass flow of dissolved sucrose into the sieve element at the source, lowered hydrostatic pressure, diffusion of sucrose to sink, active unloading
