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.
Sugars are transported in the form of sucrose. The transport of sucrose and amino acids in the phloem, from regions of production to regions of storage or use, is known as translocation. Translocation involves the transport of dissolved substances from a source to a sink inside a plant.
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...
Translocation is the movement of assimilates around the plant from the source to the sink. Translocation is bidirectional, so dissolved solutes can move either up or down the plant. The phloem consists of sieve tube members and companion cells, which carry out translocation.
