<P> In cell biology , the cytoplasm is the material within a living cell , excluding the cell nucleus . It comprises cytosol ( the gel - like substance enclosed within the cell membrane ) and the organelles -- the cell 's internal sub-structures . All of the contents of the cells of prokaryotic organisms ( such as bacteria , which lack a cell nucleus ) are contained within the cytoplasm . Within the cells of eukaryotic organisms the contents of the cell nucleus are separated from the cytoplasm , and are then called the nucleoplasm . The cytoplasm is about 80 % water and usually colorless . </P>
