Root ::
Root (n.) The
descending, and
commonly branching, axis of a
plant, increasing in
length by
growth at its
extremity only, not
divided into
joints, leafless and
without buds, and
having for its
offices to fix the plant in the
earth, to
supply it with
moisture and
soluble matters, and
sometimes to serve as a
reservoir of
nutriment for
future growth. A true root,
however, may never reach the
ground, but may be
attached to a wall, etc., as in the ivy, or may hang
loosely in the air, as in some
epiphy
