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.
Organic materials, mainly produced in the leaves, are moved around the plant in the living cells of the phloem by a process called translocation. Unlike xylem (which is composed of dead cells), the phloem is composed of still-living cells that transport sap .
The stem, root and leaves form an organ system that transports substances into, around and out of a plant. The leaves are the main organ of photosynthesis. Part of Combined Science...
Translocation (botany) facts. Translocation in vascular plants means the movement of organic molecules and some mineral ions. Movement of water from the soil to the leaves occurs in xylem vessels as the result of Transpiration.
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 …
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.
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.
