The movement of dissolved sugars and other organic substances through a plant's phloem from sources to sinks.

The movement of dissolved food molecules, particularly sugars, through phloem to other parts of a plant.

Translocation is the movement of these dissolved food molecules through phloem to other parts of the plant. For example, sugars may be delivered to growing tissues for immediate use or to storage organs, where they can be stored as starch. Unlike the upward transpiration stream in xylem, translocation can carry sugars to destinations above or below the leaves.

Translocation is not necessarily downwards: sugars can move to destinations above or below the leaves.

Do not say translocation always moves downwards. State where sucrose is coming from and where it is needed or stored.

Keep the two transport processes distinct: transpiration involves water leaving the plant; translocation moves dissolved sugars through phloem.

The movement of dissolved sugars, especially sucrose, through a plant's phloem from places where they are available to places where they are used or stored.

Translocation is the movement of dissolved sucrose through the phloem. Phloem tubes are formed from living cells joined end to end. Their end walls have openings, called sieve plates, through which the sugary solution can pass.

Plants transport dissolved sugars, particularly sucrose, through phloem. This process is translocation. Sugars are loaded into the phloem at a source and transported to a sink, where they are used for growth or stored.

The movement of dissolved sugars and other organic substances through phloem from one part of a plant to another.

The movement of sugars and other dissolved nutrients through phloem from where they are supplied to where they are needed or stored.

Translocation moves sugars dissolved in water through phloem from source to sink. Unlike the root-to-leaf journey in xylem, the direction in phloem depends on where the source and sink are; it is not always downwards.
