Geotropism
Geotropism Ge*ot"ro*pism, n. [Gr. ge`a, gh^, the earth + ? to
turn.] (Biol.)
A disposition to turn or incline towards the earth; the
influence of gravity in determining the direction of growth
of an organ.
Note: In plants, organs which grow towards the center of the
earth are said to be positively geotropic, and those
growing in the opposite direction negatively geotropic.
In animals, geotropism is supposed by some to have an
influence either direct or indirect on the plane of
division of the ovum.
