Cell (biology) The cell is the structural and functional unit of all living organisms, and is sometimes called the building block of life.. Some organisms, such as bacteria, are unicellular, consisting of a single cell. Other organisms, such as humans, are multicellular, (humans have an estimated 100 trillion cells; a typical cell size is 10 Âµm, a typical cell mass 1 nanogram). The largest known cell is an ostrich egg.
Quick Answer. The basic unit of life is the cell. In 1838, scientists Theodor Schwann and Matthias Schleiden came up with the original version of the cell theory, which concluded that the basic unit of living things is the cell. Robert Hooke first saw these units in his microscope study of slices of cork and named them cells..
