• Define translocation in terms of the movement of sucrose and amino acids in phloem: from regions of production (source) to regions of storage or to regions where they are used in respiration or growth (sink) • Explain that some parts of a plant may act as a source and a sink at different times during the life of a plant
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 · Translocation is the movement of materials in plants from the leaves to other parts of the plant. Nutrients, mainly sugars, are created in the leaves during photosynthesis.
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.
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.
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.
13 Μαρ 2021 · Translocation is movement of solutes from a source to a sink. A source is anywhere that the solute is produced, for example sucrose is produced in leaves using glucose from photosynthesis.
