# Cytoplasm --- **Cytoplasm** is a jell-like [[body fluids|fluid]] found in every living [[cell]]. In [[eukaryote|eukaryotic cells]] is specifically that which is not held by the [[nucleus|nuclear envelope]]. As prokaryotes do not have any of these structures, it is just everything incide the [[plasma membrane]]. ## Cytosol **Cytosol** is the matrix of the cytoplasm. It is a gel-like, water-based solution containing ions, small molecules, and macromolecules. It can be very hard to distinguish between cytosol and cytoplasm, so it is important to remember that the cytoplasm includes *everything* in between the [[plasma membrane]] and the [[nucleus|nuclear envelope]] (if applicable), such as the mitochondria and ribosomes. The cystol is *just the fluid component* of the cytoplasm. ___
