    Is cytosol the same as cytoplasm?

    Hi Thaheera,

    Cytoplasm refers to EVERYTHING found between the nucleus and the plasma membrane, including the cytosol, organelles, and the cytoskeleton.

    Whereas cytosol refers to ONLY the AQUEOUS part of the cell consisting of ions and organic compounds (e.g. sugars, amino acids and proteins).
