A spheroidal body growing from a plant either above or below the ground (usually below), which is strictly a bud, consisting of a cluster of partially developed leaves, and producing, as it grows, a stem above, and roots below, as in the onion, tulip, etc. It differs from a corm in not being solid.
A name given to some parts that resemble in shape certain bulbous roots; as, the bulb of the aorta.
An expansion or protuberance on a stem or tube, as the bulb of a thermometer, which may be of any form, as spherical, cylindrical, curved, etc.
Once the subject matter of rock n' roll changed from cars and pop love songs to songs about really true love and the blues and death and mortality, this light bulb went off in my head and I went, 'Oh, that's what they're doing. That's kind of - that's art.' David Chase
This revolution, the information revoultion, is a revolution of free energy as well, but of another kind: free intellectual energy. It's very crude today, yet our Macintosh computer takes less power than a 100-watt bulb to run it and it can save you hours a day. What will it be able to do ten or 20 years from now, or 50 years from now? Steve Jobs
