B cell |
a type of white blood cell, produced in the bone marrow, that makes antibodies that fight off disease. |
brain cell |
a cell in the brain, esp. a neuron. |
cell block |
a unit consisting of multiple cells in a prison. |
cell line |
a cell culture produced from a single cell. |
cell membrane |
the semipermeable membrane that encloses the contents of a cell; plasma membrane. |
cell phone |
a mobile telephone that operates using radio signals and therefore requires no wires. A cell phone is part of a system composed of many low-power radio transmitters located in "cells" across a region and will receive a radio signal from whichever transmitter in the system is closest; cellular phone. |
cell wall |
the rigid outermost layer of a plant cell, which is made of cellulose. |
dry cell |
an electric cell in which the electrolyte is in a paste, treated with an absorbent, or otherwise protected against spilling. |
fuel cell |
any of various devices in which continuous electrical energy is produced from the reaction between a fuel, such as liquid hydrogen, and an oxidant. |
germ cell |
a cell whose principal function is reproduction; egg or sperm cell. |
hot cell |
an enclosure designed to house radioactive materials in a safe manner so they can be worked on or tested by remote control. |
nerve cell |
a neuron. |
padded cell |
a room, cell, or the like that is extensively lined with padding and in which potentially violent prisoners or patients may be confined without risk of injuring themselves. |
photoelectric cell |
an electric cell in which the force of the current changes according to the variations of light or other radiation falling on it; electric eye. |
photovoltaic cell |
a cell that produces electromotive force when it is exposed to radiation, esp. light; solar cell. |
primary cell |
a battery cell in which electric current is generated by an irreversible electrochemical reaction, and which therefore cannot be recharged efficiently. |
red blood cell |
a disk-shaped cell, usu. lacking a nucleus, that carries oxygen to the body's tissues; erythrocyte. |
selenium cell |
a photoconductive cell made by placing a thin strip of selenium between two metal electrodes. |
sickle cell anemia |
a hereditary form of anemia caused by the presence of abnormal sickle-shaped red blood cells and abnormal hemoglobin, resulting in abdominal pain and leg ulcers. |
solar cell |
