Detailed explanation-1: -A bulb is an underground stem with fleshy and scale-like layers surrounding a centre bud. The base of the bulb consists of a cluster of adventitious roots. The shoots of the bulbs are developed from the lateral buds and their leaves are capable of storing food.

Detailed explanation-2: -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-3: -bulb, in botany, a modified stem that is the resting stage of certain seed plants, particularly perennial monocotyledons. A bulb consists of a relatively large, usually globe-shaped, underground bud with membraneous or fleshy overlapping leaves arising from a short stem.

Detailed explanation-4: -rhizome, also called creeping rootstalk, horizontal underground plant stem capable of producing the shoot and root systems of a new plant. Rhizomes are used to store starches and proteins and enable plants to perennate (survive an annual unfavourable season) underground.

Detailed explanation-5: -A bulb is a short stem with fleshy leaves or leaf bases. The leaves often function as food storage organs during dormancy.
