Question

Sinks of mineral absorption in plants

Answer 1

Source-sink relation in plants. ... Functionally a plant can be divided into source and sink, sources being the parts where net fixation of carbon dioxide occurs, and sinks being the sites where assimilates are stored or used. Allocation of assimilates between plant parts occurs via transport in the phloem.

Answer 2

Plants need an energy source to grow. ... Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.
