WebbSink regions play a central role in determining assimilate distribution patterns. Two factors are discussed which have a strong effect on the ‘sink strength’ of a sink, viz. phloem unloading and turgor-sensitive transport. ‘Sink strength’ may be defined as the capacity of phloem in the sink region to import assimilates from other parts of the plants and to … Webb13 feb. 2024 · Phloem Definition.

WebbPhloem Transport Food is synthesized in the green parts of a plant. The non-green parts are depended on the photosynthetic cells for nourishment. The food in the form of sucrose is transported by the vascular tissue phloem. Let us learn a bit more about phloem transport. The transportation occurs in the direction of the source to sink. WebbPhloem is a specialised living tissue that transports amino acids and sugars from the leaves (source) to the growing parts of the plant (sink) in a process called translocation. …
