In botany, a bulb is a short underground stem with fleshy leaves or leaf bases [1] that function as food storage organs during dormancy. In gardening, plants with other kinds of storage organ are also called ornamental bulbous plants or just bulbs.

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.

Sep 20, 2024 · A bulb is comprised of a plant's stems and leaves. The bottom of the bulb is a compacted stem, with roots growing from it. Layers of nutrient-filled leaves sit at the bottom of the bulb and surround a bud that eventually becomes a flower.

Feb 24, 2023 · A bulb is a specialized underground organ consisting of a short, fleshy, stem axis (basal plate), bearing at its apex a growing point or a flower primordium enclosed by thick fleshy scales. Bulbs are mostly produced by monocots.

Mar 17, 2020 · Bulb is commonly used to describe geophytes, or plants that produce specialized underground stems where buds form. Storing carbohydrates for growth and keeping buds below ground helps the plant survive adverse conditions above ground such as fire, animal browsing or annual climactic cycles.

Mar 23, 2020 · A bulb is a plant with an underground highly condensed discoid stem surrounded by fleshy leaves or leaf bases that store food. A bulbil is an aerial stem modification that develops from the axillary bud of a plant or in place of an inflorescence or flower.

A bulb is roughly spherical or pyriform in outline. It may be spherical, elongated or vertically compressed. Stem: The bulb is a condensed underground shoot. The corm is an underground stem. Buds: The buds of a bulb are borne internally. The buds of a corm are borne externally. Nodes: Clear-cut nodes are absent. A corm bears distinct circular ...

Corms often resemble true bulbs without the layers. Another difference of note is that the bulb’s primary storage organ is the leaf tissue (what we see as “layers” in the onion) while the corm’s is the stem. Some corms have fuzz on the surface and all have a solid interior.

Feb 24, 2023 · The basal plate is the compact, fleshy stem found in bulbs. It is the location where the new organs form on the bulb. Meristems that form on the basal plate include those for vegetative and flowering stem, new buds that will form offsets, and the root system that arises as adventitious roots.

Jul 15, 2018 · The main difference between bulbs corms tubers and rhizomes is that the bulbs consist of modified leaves, which store nutrients while corms are swollen stem bases and tubers are thick underground stems, and rhizomes are swollen stems that grow horizontally.
