• 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 · Translocation: Extended. The soluble products of photosynthesis are sugars (mainly sucrose) and amino acids. These are transported around the plant in the phloem tubes which are made of living cells (as opposed to xylem vessels which are made of dead cells)
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 …
Transport over longer distances proceeds through the vascular system (the xylem and the phloem) and is called translocation. An important aspect that needs to be considered is the direction of transport. In rooted plants, transport in xylem (of water and minerals) is essentially unidirectional, from roots to the stems.
Translocation - the process of transporting sugars and nutrients through the phloem. Source - the location that the sugars or nutrients are loaded during translocation. Sink - the location that the sugars or nutrients are unloaded during translocation. Active transport - the net movement of particles against a concentration gradient using energy.
Plants have a transport system made up of xylem and phloem vessels. These transport nutrients from the roots of the plant to the stem and leaves, and vice versa. The xylem is used to transport water and mineral ions through plants from the roots in. transpiration.
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...
