Question

The following can act as both source and
sink
(A) Growing Regions
(B) Unmodified leaves
(C) Storage organs
(D) Unmodified roots​

Answer 1

(C) Storage organs can act as both source and sink

Explanation:

1. a storage organ during the exporting phase of its development. For example, the storage root of the biennial wild beet (Beta maritima) is a sink during the growing season of the first year, when it accumulates sugars received from the source leaves.

2.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).

3.Sources is the nutrient-rich regions that supply sugars for the rest of the plant are called the sources. Sources include the leaves, where sugar is generated through photosynthesis.

4.When they are high in supplies, the nutrient storage areas, such as the roots and stems, can also function as sources.
