HORTICULTURE

Detailed explanation-1: -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-2: -The phloem is the means by which the products of photosynthesis are transported to non-photosynthetic parts of the plant, such as the roots, and to developing leaves, nectaries, fruits and seeds (Baker and Milburn, 1989).

Detailed explanation-3: -These sugars are transported across the plant by the phloem, a mechanism known as translocation. Sinks are sugar distribution points such as roots, young shoots, and developing plants. The product of photosynthesis is transported from source of production to the storage organs through Phloem.
