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) (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.
Distinguish between sources and sinks and provide examples of each. Explain the process of phloem loading, distinguishing between apoplastic and symplastic pathways. Explain how assimilate translocations through the phloem according to the pressure-flow hypothesis.
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.
2 Ιουν 2022 · Assimilates are moved through a plant by the process of translocation. They are moved from source to sink. Here are examples of sources and sinks
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 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. The main substance moved in this way is sucrose, a type of sugar. Process.
