    Reproduction System
    In humans, non-motile and food storing germ cells is ________ and the motile germ cell is:
    The egg cell, or ovum (plural ova), is the female reproductive cell (gamete) in sexually producing organisms. The egg cell is typically not capable of active movement, and it is much larger (visible to the naked eye) than the sperm. The motile germ cell is sperm. The primary function of the sperm is to pass on the necessary biological information required to produce a new organism. This is true for all the organisms which reproduce sexually.
