The movement of sucrose and other substances like amino acids around a plant is called translocation . In general, this happens between where these substances are made (the sources) and where they are used or stored (the sinks): from sources in the root to sinks in the leaves in early spring time.
Translocation is the process by which plants deliver minerals, plant growth hormones, water, and organic substance over long distances throughout the plants (from leaves to other parts). ... These food nutrients are translocated in the form of solutes in a solution known as phloem sap.
