Cell theory, developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and function in all organisms, and that all cells come from pre-existing cells. Organisms are broadly grouped into eukaryotes and prokaryotes.
A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks.
Cells consist of a variety of internal and external structures that perform specialized functions necessary for survival and reproduction. These components vary depending on whether the cell is prokaryotic or eukaryotic, and whether it belongs to a plant, animal, fungus, or protist.
