Webb25 jan. 2024 · Translocation in Phloem. The movement of various molecules, like sucrose, amino acids, etc., through phloem in a plant, is called translocation in the phloem. The translocation in the phloem is not affected due to gravity. Sucrose is instead translocated from the point of supply (leaf) to the point of metabolism or storage, referred to as a sink. WebbSo, by using energy, the sugars need to be transported into the phloem. And because energy is utilized for this process, we say it's an active process. Now see what happens. …

Specialized plasmodesmal connections that regulate phloem entry and exit are central to all of these processes. Webb8 juni 2024 · Translocation is the process within plants that functions to deliver nutrients and other molecules over long distances throughout the organism. Translocation occurs within a series of cells known as the phloem pathway, or phloem transport system, with phloem being the principal food-conducting tissue in vascular plants.

Although its primary function is transport of sugars, phloem may also contain cells that have a mechanical support function. These are sclerenchyma cells which generally fall into two categories: fibres and sclereids. Both cell types have a secondary cell wall and are dead at maturity.
