The cell is the fundamental organizational unit of life. All living things are composed of cells, which then further subdivide based on the presence or absence of the nucleus, into two types: eukaryotic cells (Greek, Eu=true, karyo=nut, nucleus) - these cells are present in all the human, animal and plants with a clear, distinct nucleus. Prokaryotic cells are some bacteria and blue-green algae which do not contain a clear and distinct nucleus, but the nuclear material is spread within the cytoplasm. The cells with a similar structure and function come together to form tissue. The tissues basically classify as four different types, namely, the epithelial, connective, muscular, and nervous tissues. A combination of these tissues is present in an organ. The total number of cells, their type, size, and shape finally determines the size, structure, and function of each particular organism.[1]

Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell may be a complete organism in itself, such as a bacterium, or it may acquire a specialized function, becoming a building block of a multicellular organism.
