NEET BIOLOGY

Detailed explanation-1: -Sink organs include tubers, roots, rapidly growing tissues, or even old and shaded leaves. In a potato plant, the sink of greatest interest is the tuber.

Detailed explanation-2: -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.

Detailed explanation-3: -Seeds, fruits, flowers, roots, and storage organs act as sinks in fully grown plants.

Detailed explanation-4: -Source-to-sink transport of sugar is one of the major determinants of plant growth and relies on the efficient and controlled distribution of sucrose (and some other sugars such as raffinose and polyols) across plant organs through the phloem.
