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.
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...
Key learning points. 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.
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.
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.
Translocation is the process by which food produced in photosynthesis is transported from the leaves to the growing regions of plants and storage organs. Features of translocation are: Phloem tubes
During transpiration plants move water from the roots to their leaves in xylem vessels. Glucose made in the leaves through photosynthesis is then moved to all cells in phloem vessels by...
