Cytoplasm is the jelly-like material found inside all cells. It is mostly water, and it provides a place for the cells essential chemical reactions to take place. It also helps support the organelles, like the nucleus and mitochondria,
The cytoskeleton is the "skeleton" of the cell. It is made of three different types of protein filaments: microfilaments, intermediate filaments, and microtubules. They each have a slightly different role, but as a whole, the cytoskeleton is responsible for giving structure and support to the cell and allowing it to move.
