There are two points: the foci.
focus
No there can never be a single point. But yes there are two such points called foci( each called focus) that helps to define an ellipse. An ellipse can then be defined as a curve which is actually the locus of all points in a plane,the sum of whose distances from two fixed points (the foci) is a given(positive)constant . This is further expressed mathematically to obtain the equation of an ellipse.
The two fixed points are the foci but these do not define the shape of the ellipse. You also need to know the eccentricity.
An ellipse is a shape on which the sum of the distances from every point to two points inside called the foci (focuses) is always the same number. A circle is an ellipse with both foci (focuses) at the same point.

The two foci are necessary to define the location of an ellipse, but the shape depends on the eccentricity, which is related to the lengths of the two axes.
It is difficult to say since there is no such word as elipse. It could be a failed attempt at ellipse or eclipse and the answer will depend on which it was meant to be.
The shape that defines the orbit of planets around the sun is an ellipse. An ellipse is a closed curve in which the sum of the distances from any point on the curve to two fixed points (foci) is constant.
Ellipse is a term for an oval. Specifically it is a shape where the sum of the distance of every point on the ellipse to two points, called the foci, is equal.
An ellipse is a shape on which the sum of the distances from every point to two points inside called the foci (focuses) is always the same number. A circle is an ellipse with both foci (focuses) at the same point.
A circle is an ellipse with an eccentricity of zero. Both foci of that ellipse are at the same point. In the special case of the circle, that point is called the "center".
Ben drew an ellipse as a plane curve with edges not parallel to its axis.
Both foci of any ellipse are always in the same plane.If they're both at the same point, then the ellipse is a circle.
