The cell from the Latin word cellula meaning small room is the basic structural and functional unit of lifeEvery cell consists of a cytoplasm enclosed within a membrane which contains many biomolecules such as proteins and nucleic acids. For example components of the bacterial cell wall can trigger severe and immediate attacks by neutrophils.
