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.
The worksheet prompts learners to identify and describe these components in evergreen and tropical plants, and to explain the mechanisms driving the direction of flow in the phloem. It also includes a concise definition question to ensure students can articulate what translocation is.
8 Απρ 2019 · Which process is an example of translocation? A absorption of water by the roots and its movement through the xylem to the leaves. B loss of water from the leaves as it evaporates into the air. C movement of sucrose from the leaves through phloem to other parts of the plant.
• 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 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 …
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...
31 Μαΐ 2024 · This worksheet covers transport in plants. Specifically how they transport sugars via the phloem (translocation) and water via the xylem (transpiration). We also cover the factors that affect the rate of transpiration: light intensity, temperature, humidity and air flow.
