Nucleoplasm is the liquid which surrounds the nucleolus within the nucleus. It is very similar to cytoplasm in the way that it is mostly salt water. nucleoplasm is said to also contain subnuclear bodies. Which perform various tasks within the nucleus. They can be compared to organelles by what they do in a cell. Because of the miniscule size, they can only be seen to some degree by an Electron microscope. Because of this, not much is known about them.
