Explanation:

A rocket carries both fuel (which may be solid or liquid) and oxygen in contrast to a jet engine.
Therefore it does not suck in air from the front. It burns the fuel with the oxygen, and eject it at very high velocities backward. This momentum is used to both lift and propel the rocket. There are no wings for uplift. Any wings are for steering purposes.
A rocket is generally much more powerful and wasteful than a jet engine. Most airplanes cannot possibly climb vertically, while rockets are designed to do that. A jet airplane cannot function outside the atmosphere, but a rocket can since it carries its own fuel and oxygen.
