Within a cells nucleus is a special structure called the nucleolus that houses the ribosomal machinery. A unicellular organism that lacks a nucleus and membrane bound organelles. Organelles likely evolved from bacteria that were endocytosed by nucleated ancestral cells. One of several bodies with a specialized function that is suspended in the cytosol of the cell. However most phase-separating systems PS demand multiple partners in biological conditions. RETURN to CELL DIAGRAM.
