- a green, somewhat translucent variety of chalcedony
- the fluid part of blood, lymph, milk, or intramuscular liquid; esp., the fluid part of blood, as distinguished from the corpuscles, used for transfusions
- any highly ionized gas, as that in a glowing fluorescent lamp
- a unique form of matter, as in a star, consisting of highly energized, freely moving ions and electrons
- a flat-screen, high-definition video display consisting of a grid of tiny, gas-filled fluorescent cells that emit colors of varying intensities as the gas is ionized by an electrical signal
Origin of plasmaGerman ; from Classical Greek something molded ; from plassein, to form: see plastic
- a. The clear, yellowish fluid portion of blood, lymph, or intramuscular fluid in which cells are suspended. It differs from serum in that it contains fibrin and other soluble clotting elements.b. Blood plasma, especially when sterilized and depleted of cells for transfusion.
- Protoplasm or cytoplasm.
- The fluid portion of milk from which the curd has been separated by coagulation; whey.
- Physics An electrically neutral, highly ionized phase of matter composed of ions, electrons, and neutral particles. It is distinct from solids, liquids, and gases.

plasma - Computer Definition
One of four states of matter (solid, liquid, plasma and gas). The plasma state is a gas that is heated to the point where it begins to release electrons. Although plasma occurs naturally on the sun and other stars, it is artificially produced in fluorescent lights and plasma displays by electrically charging a gas in order to release ultraviolet light. See plasma display and flat panel TV.
