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...
21 Νοε 2023 · An example of translocation in plants is the movement of sugars from sugar sources to sugar sinks. Sugar sources include sugars either created through photosynthesis or stored...
Organic materials, mainly produced in the leaves, are moved around the plant in the living cells of the phloem by a process called translocation. Unlike xylem (which is composed of dead cells), the phloem is composed of still-living cells that transport sap.
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.
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.
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. Water moves into the phloem cells by osmosis, which increases the pressure and pushes the sugars along the phloem tube.
What is translocation in plants? Translocation is the transport of dissolved sugars around a plant in the phloem. Plants make glucose by photosynthesis. Carbon dioxide diffuses into the air spaces in the leaf through the stomata. The oxygen produced by photosynthesis diffuses out of the leaf, through the stomata. Water is transported to the ...
