Plants transport organic compounds from sources to sinks
Active transport is used to load organic compounds into phloem sieve tubes at the source
High concentrations of solutes in the phloem at the source lead to water uptake by osmosis
Incompressibility of water allows transport along hydrostatic pressure gradients
Raised hydrostatic pressure causes the contents of the phloem to flow towards sinks
