In biology, a discrete, membrane-bound portion of living matter, the smallest unit capable of an independent existence. All living organisms consist of one or more cells, with the exception of viruses. Bacteria, protozoa, and many other microorganisms consist of single cells, whereas a human is made up of billions of cells. Essential features of a cell are the membrane, which encloses it and restricts the flow of substances in and out; the jellylike material within, the cytoplasm; the ribosomes, which carry out protein synthesis; and the DNA, which forms the hereditary material.
1. A room where a prisoner is kept; SYN. jail cell, prison cell.
2. Small room is which a monk or nun lives; SYN. cubicle.
3. Any small compartment.
4. The basic structural and functional unit of all organisms; cells may exist as independent units of life (as in monads) or may form colonies or tissues as in higher plants and animals.
5. A device that delivers an electric current as the result of a chemical reaction; SYN. electric cell.
6. A small unit serving as the nucleus of a larger political movement; SYN. cadre.
A small cell.
ETYM Greek, a creator.
Minute mass of protoplasm in cell.
General name for a cell organelle of plants that is enclosed by a double membrane and contains a series of internal membranes and vesicles. Plastids contain DNA and are produced by division of existing plastids. They can be classified into two main groups: the chromoplasts, which contain pigments such as carotenes and chlorophyll, and the leucoplasts, which are colorless; however, the distinction between the two is not always clear-cut.
Chloroplasts are the major type of chromoplast. They contain chlorophyll, are responsible for the green coloration of most plants, and perform photosynthesis. Other chromoplasts give flower petals and fruits their distinctive color. Leucoplasts are food-storage bodies and include amyloplasts, found in the roots of many plants, which store large amounts of starch.
Any of various small particles in the cytoplasm of the cells of plants and some animals containing pigments or starch or oil or protein.
ETYM Latin, from Greek, a case to put anything in. Related to Tick a cover.
1. A case or sheath especially a pollen sac or moss capsule; SYN. sac.

1. The intersection of a row and a column in a spreadsheet. Each row and column in a spreadsheet is unique, so each cell can be uniquely identified—for example, cell B17, at the intersection of column B and row 17. Each cell is displayed as a rectangular space that can hold text, a value, or a formula.
2. An addressable (named or numbered) storage unit for information. A binary cell, for example, is a storage unit that can hold 1 bit of information—that is, it can be either on or off.
3. A fixed-length packet, the basic transmission unit on high-speed networks, such as ATM. See also ATM.
4. Coverage area for wireless phones served by a single base station (cell tower), usually surrounded by six other cells. As a wireless phone moves across the boundary between cells, the conversation is handed from one cell to the next. Cells may be less than a half mile or more than 15 miles in radius, depending on the volume of wireless calls or the presence of large buildings or terrain that might interfere with signals.
