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.
Cell biology is the study of the structural and functional units of cells. Cell biology encompasses both prokaryotic and eukaryotic cells and has many subtopics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition.
La biología celular abarca tanto las células procariotas como las eucariotas y se puede dividir en muchos subtemas que pueden incluir el estudio del metabolismo celular, la comunicación celular, el ciclo celular, la bioquímica y la composición celular, la interacción con el ambiente y su ciclo vital .
