Entomology definition of Cell: any space between or bounded by veins: in the
Comstock system the cells derive their names from the vein
forming the Tupper margin: e.g. all just below the radius are
radial cells; and they are numbered from the base outward, as
radial 1, 2, etc.: the living unit; protoplasm differentiated
into cytoplasm and nucleus, from which units all but the lowest
plants and animals are developed by division and consequent
increase into a multicellular condition: a compartment or
