Torus vs Ellipsoid - What's the difference?

torus | ellipsoid |

In mathematics terms the difference between torus and ellipsoid

is that torus is the standard representation of such a space in 3-dimensional Euclidean space: a shape consisting of a ring with a circular cross-section: the shape of an inner tube or hollow doughnut while ellipsoid is of or pertaining to an ellipse.

In botany terms the difference between torus and ellipsoid

is that torus is the end of the peduncle or flower stalk to which the floral parts (or in the Asteraceae, the florets of a flower head) are attached; see receptacle while ellipsoid is having the tridimensional shape of an ellipse rotated on its long axis.

As nouns the difference between torus and ellipsoid

is that torus is a topological space which is a product of two circles while ellipsoid is a surface, all of whose cross sections are elliptic or circular (includes the sphere.

As an adjective ellipsoid is
