A dependency is a package required by another package to complete its own functionality. There are two popular packaging mechanisms:

debian

RPM

Both these mechanisms use the concept of dependencies. Ubuntu uses debian packaging.

If A and B are two packages and A is a dependency for B, satisfying dependency means installing the version of package A as required by B. So, if you just remove B, A will still be there on your system. If you do sudo apt-get autoremove and no other package requires A, then A will be removed. However, note that if you remove A, B will be automatically removed since B depended on A.
