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.
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 …
2 Ιουν 2022 · Although translocation could refer to the transport of substances in the xylem and phloem, as it means ‘moving from one place to another,’ it is more commonly connected with the transport of assimilates in the phloem tissue
27 Αυγ 2022 · Definition. noun. (1) A change of location; displacement; a transfer of location. (2) (genetics) Chromosomal translocation, that is a chromosomal segment is moved from one position to another, either within the same chromosome or to another chromosome. (3) (botany) Transport of soluble food material from one plant to another via phloem or xylem.
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. 8.1 TRANSPORT IN PLANTS.
Definition and Overview. Translocation refers to the transport of soluble organic compounds within a plant. This process occurs in the plant’s phloem tissue. These compounds are often referred to as assimilates or photosynthates.
Phloem - specialised vessels in plants that transport sugar, amino acids and other nutrients. 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
