This is a printable worksheet called Translocation in Plants and was based on a quiz created by member Hannah Humphreys
The xylem transports water and mineral ions from root to leaf, while the phloem transports dissolved sugars throughout the plant. Both are key aspects of transport in plants and need to be understood for AQA's Biology Topic 2.
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.
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 Transport over...
• 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
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.
21 Νοε 2023 · A simple definition of translocation is the movement of materials from one area to another. In plants, plant translocation involves the movement of sugars from sources to sinks.
