Explore the wonderful world of translocation in plants with our Translocation in Plants Information Poster: perfect for revising Topic 2 in AQA Biology. This eye-catching poster explains the process of translocation and the structure of the phloem in plants.
8 Ιαν 2014 · Translocation in plants. Translocation is the transport of organic substances like sugars through the phloem tissue of plants. Assimilates are produced by plant cells and loaded into sieve tube elements, with help from companion cells, for long-distance transport.
• 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)
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.
Key learning points. Sugars, amino acids and other organic substances (nutrients) are transported in phloem. 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.
13 Μαρ 2021 · Translocation is the movement of solutes from source to sink through the phloem sieve tubes. Sucrose is actively loaded into companion cells using co-transport with H + ions.
