24 Σεπ 2024 · Translocation: Extended. The soluble products of photosynthesis are sugars (mainly sucrose) and amino acids. These are transported around the plant in the phloem tubes which are made of living cells (as opposed to xylem vessels which are made of dead cells)
Translocation is the movement of the substance in the phloem (assimilate). Phloem loading may be apoplastic or symplastic. The pressure-flow hypothesis explains how translocation is driven by phloem …
Sugars are transported in the form of sucrose. The transport of sucrose and amino acids in the phloem, from regions of production to regions of storage or use, is known as translocation. Translocation involves the transport of dissolved substances from a source to a sink inside a plant.

Translocation starts at a source, such as a leaf where sugars are made. Sugars are transported into phloem by active transport across the membranes of the living phloem cells. Water moves into the phloem cells by osmosis, which increases the pressure and pushes the sugars along the phloem tube.
Translocation refers to the transport of soluble organic compounds within a plant. This process occurs in the plant’s phloem tissue. These compounds are often referred to as assimilates or photosynthates. The main substance moved in this way is sucrose, a type of sugar.
27 Αυγ 2022 · Definition. noun. (1) A change of location; displacement; a transfer of location. (2) (genetics) Chromosomal translocation, that is a chromosomal segment is moved from one position to another, either within the same chromosome or to another chromosome. (3) (botany) Transport of soluble food material from one plant to another via phloem or xylem.
