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.
• 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)
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.
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,...
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.
Translocation is the movement of dissolved food substances up and down the phloem. Substances such as glucose and amino acids, may be required all around the plant. They may be needed at the roots, the leaves or at buds.
13 Μαρ 2021 · Translocation is movement of solutes from a source to a sink. A source is anywhere that the solute is produced, for example sucrose is produced in leaves using glucose from photosynthesis.
