• Define translocation in terms of the movement of sucrose and amino acids in phloem: from regions of production (source) to regions of storage or to regions where they are used in respiration or growth (sink) • Explain that some parts of a plant may act as a source and a sink at different times during the life of a plant
24 Σεπ 2024 · The cells are joined end to end and contain holes in the end cell walls (called sieve plates) which allow easy flow of substances from one cell to the next. The transport of sucrose and amino acids in the phloem, from regions of production to regions of storage or use, is called translocation.
This eye-catching poster explains the process of translocation and the structure of the phloem in plants. Our Translocation in Plants Information Poster could be displayed alongside our Transpiration Information Poster as a handy reminder for students of the different transport processes in plants.

Plant organisation - AQA Synergy Translocation. Plant cells, tissues and organs are adapted to their functions. The stem, root and leaves form an organ system that transports substances into,...
21 Νοε 2023 · An example of translocation in plants is the movement of sugars from sugar sources to sugar sinks. Sugar sources include sugars either created through photosynthesis or stored in...
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.
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.
