The vast majority of eukaryotic cells have a single nucleus, though some cells may have more than one nucleus, either temporarily or permanently, and in some organisms there exist certain cell types (e.g. mammalian erythrocytes) which lose their nuclei upon reaching maturity, effectively becoming anucleate. The nucleus is one of the defining ...

The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
