Difference between Ellipsoid and Spheroidal

ELLIPSOID vs SPHEROIDAL: NOUN

A surface whose plane sections are all ellipses or circles
Such a surface used as a model of the shape of the earth.
A surface, all of whose cross sections are elliptic or circular (includes the sphere)
A spheroid; a solid figure generated by the revolution of an ellipse about one of its axes. It is called a prolate spheroid, or prolatum, when the ellipse is revolved about the major axis, and an oblate spheroid, or oblatum, when it is revolved about the minor axis.
A solid, all plane sections of which are ellipses or circles. See conoid, n., 2 (a).
In geometry, a solid figure all plane sections of which are ellipses or circles.
In anthropology, a cranium the norma verticalis of which has an ellipsoidal form.
A geometric surface, all of whose plane sections are either ellipses or circles.

In the form of an ellipse
Having the form of a spheroid.
The state of a liquid, as water, when, on being thrown on a surface of highly heated metal, it rolls about in spheroidal drops or masses, at a temperature several degrees below ebullition, and without actual contact with the heated surface, -- a phenomenon due to the repulsive force of heat, the intervention of a cushion of nonconducting vapor, and the cooling effect of evaporation.
Like a spheroid. Roughly spherical, approximately round, roughly ball shaped.
Having the nature or shape of an ellipsoid

In entomology, round and prominent, appearing like a ball or sphere partly buried in the surface: as, spheroidal eyes: spheroidal eoxæ.
In crystallography, globose; bounded by several convex faces.
Of or pertaining to, or having the form of, a spheroid.
In petrography, noting the cracking or parting of rocks upon shrinking, commonly from cooling, whereby they break into spheroidal masses. It is the same phenomenon as perlitic cracking in volcanic glasses. The term is sometimes used as a synonym of orbicular as applied to certain granites and diorites.

When the Distances field is set to Ground or Ellipsoid, the General Survey software attempts toperform calculations on the ellipsoid.
Fortunately, a cylinder may be considered an elongated ellipsoid and a disc, a fiat ellipsoid.
An ellipsoid represents where water can go, with a long thin ellipsoid indicating good diffusion for water along the long axis of that ellipsoid.

Pollen grains generally are spheroidal or somewhat elongated and have a very durable outer wall.
All lens and primary mirror surfaces are spheroidal which eases construction.
