What is the difference between ellipse and ellipsoid?

is that ellipsoid is (mathematics) a surface, all of whose cross sections are elliptic or circular (includes the sphere) while ellipse is (geometry) a closed curve, the locus of a point such that the sum of the distances from that point to two other fixed points (called the foci of the ellipse) is constant; ...
