Detailed explanation-1: -The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks. Sinks include areas of active growth (apical and lateral meristems, developing leaves, flowers, seeds, and fruits) or areas of sugar storage (roots, tubers, and bulbs).
Detailed explanation-2: -Note: Roots and developing seeds both act as sugar sink. The sugar is stored in the form of energy in roots which are acting as sinks.
Detailed explanation-3: -Answer and Explanation: The structure that transports sugar from the leaves to the roots is-C) Phloem. vascular movement of substances inside the plant body. photosynthesis.
Detailed explanation-4: -The mechanism by which sugars are transported through the phloem, from sources to sinks, is called pressure flow. At the sources (usually the leaves), sugar molecules are moved into the sieve elements (phloem cells) through active transport.
