cell

Cell has several different meanings, but all of them are similar. Whether it's in a prison or in your blood (or even in the political landscape), a cell is a small room, space, or unit.

Blood is composed of countless individual cells, as are virtually all of the organs of the body: skin, liver, lungs, brain, etc. The cell is the basic unit of all biology. A cell in a prison is the room in which a prisoner lives. But did you know that a cell can also be a small group of people devoted to a larger political cause? The government's security forces are constantly on the lookout for terrorist "sleeper cells" and would love to get the members of a sleeper cell into a prison cell.

Primary Meanings of cell

1.
n
(biology) the basic structural and functional unit of all organisms; they may exist as independent units of life (as in monads) or may form colonies or tissues as in higher plants and animals
2.
n
small room in which a monk or nun lives
3.
n
any small compartment
4.
n
a small unit serving as part of or as the nucleus of a larger political movement
5.
n
a device that delivers an electric current as the result of a chemical reaction
6.
