DENDROLOGY

Detailed explanation-1: -Rhizomes are underground stems which grow beneath the surface of soil; they are frequently fleshy and serve as organs of food storage. Sometimes the rhizomes are condensed into solid swollen forms which are then known as corms. The tubers are also underground parts, which may either be modified roots or stems.

Detailed explanation-2: -Tubers are a type of enlarged structure used as storage organs for nutrients in some plants. They are used for the plant’s perennation (survival of the winter or dry months), to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction.

Detailed explanation-3: -Bulbs are underground storage organ which consists short stem with fleshy and scaly leaves. Bulb scales morphologically are the continuous sheathing leaf bases. Bulbs are produced by monocotyledons plants in which the usual structure is modified for storage and reproduction.
