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.
Sugars, amino acids and other organic substances (nutrients) are transported in phloem. Translocation starts at a source, such as a leaf where sugars are made. Sugars are transported into phloem by active transport across the membranes of the living phloem cells.
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.
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...
13 Μαρ 2021 · Translocation is the movement of solutes from source to sink through the phloem sieve tubes. Sucrose is actively loaded into companion cells using co-transport with H + ions. There is a pressure gradient from source to sink which drives mass flow.
