what is cytoplasm and cytoskeleton's function and why is it important.

Cytoplasm is a jelly-like material that fills cells

cytoskeleton is both a muscle and a skeleton, and is responsible for cell movement, cytokinesis, and the organization of the organelles within the cell.

Since this is not my area of expertise, I searched Google under the key words "cytoplasm cytoskeleton" to get these possible sources:

I hope this helps a little more. Thanks for asking.
