Difference between Source and Sink in Plants. The photosynthetically active parts of a plant are referred to as the source. The areas of active growth and areas of storage are referred to as sinks. However, a source is not always a source, and a sink is not always a sink. For example, leaves that act as sources when the plant is fully grown are ...

To describe where an essential resource is taken up or synthesized, and where it is used in a plant, biologists use the terms “source” and “sink”. A source is a location in a plant where a resource is taken up (ex. water and nutrients) or synthesized (glucose). A sink is a location where a resource is used. Fruit & Nut Research ...
Oct 31, 2023 · These sugars are transported through the plant via the phloem in a process called translocation. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks. Seeds, tubers, and bulbs can be either a source or a sink, depending on the plant’s stage of development and the season.
Sources and Sinks. Structures that produce or release sugars for the growing plant are referred to as sources. Examples include mature leaves, which produce sugar through photosynthesis, and storage organs, such bulbs, tubers, or storage roots. Sources produce or store more sugars than they need themselves and can thus export sugars.
Sep 25, 2018 · Sink activity is photoassimilate use and storage. Belowground organs of plants (e.g. roots and rhizomes) are sinks during plant growth since they cannot perform photosynthesis. Some organs are both a source and sink. Leaves are sinks when growing and sources when photosynthesizing. Rhizomes are sinks when growing but become sources in the ...
at different seasons. ' Source ' is the part of a plant where substances are produced (e.g. leaves for sucrose, amino acids) or enter the plant. 'Sink ' refers to the part of the plant where the substrate can be stored (e.g. roots or stem for starch). Leaves - sucrose is produced here. Root hairs - Nitrates are absorbed here.

Oct 6, 2023 · The terms ‘source’ and ‘sink’ are also used for other fields of research, such as studies on sedimentation and soil erosion (Cabré et al. 2020), and researchers may also use analogous terms, such as ‘ecological trap’ instead of ‘sink’ (Wallace et al. 2020).
