The products of photosynthesis (mainly the sugar sucrose) are a major component of the substance found in the phloem, called assimilate. Ions, amino acids, certain hormones, and other molecules are also found in assimilate. The movement of assimilate is called translocation, or assimilate transport.
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.
2 Ιουν 2022 · Revision notes on 3.3.9 Translocation for the OCR A Level Biology syllabus, written by the Biology experts at Save My Exams.
• 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
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.
plants is in a continuous state of flux, based on the degree of metabolic activity, the water status of the surrounding air and soil, and a variety of other factors. Water plays a crucial role in the physiological processes of plants; roles for which it is well-suited because of its special physical and chemical properties, some of which are:
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.
