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) (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 Transport over...
Translocation is the process by which materials in the plant are moved from where they are made to where they are needed. The prefix trans - means “across,” referring to the directional movement of substances, and the suffix - location refers to the places they are moved from and to.
Translocation is the movement of dissolved food substances up and down the phloem. Substances such as glucose and amino acids, may be required all around the plant. They may be needed at the roots, the leaves or at buds.
