You're probably thinking of a cone. There is some disagreement as to whether the point of a cone qualifies as a vertex.
a cone
A sphere has a total curved surface. A cylinder and a cone have a partial curved surface
a sphere has no bases and it only has one curved surface
it is a three dimensional cone , the circle is the edge of the figure and the curved side is the body of the cone, the vertex is the point of the cone
curve surface area

a cone
An ellipsoid or a toroid or other 3-dimensional objects with more than one "holes". Or simply a ... sphere.

It's a rectangle.
A paraboloid.
A cylinder.
Yes, a cylinder has both curved and flat surface. Considering a solid cylinder standing on its end, the circular base and the circular top are flat surfaces. The surface connecting the top and bottom is curved.
A cylinder !
