  substance:  tissue
  part:  cell  the basic structural and functional unit of all organisms; cells may exist as independent units of life (as in monads) or may form colonies or tissues as in higher plants and animals
     part:  cell_wall__cell_membrane__plasma_membrane  a thin membrane around the cytoplasm of a cell; controls passage of substances in and out of the cell
     part:  energid__protoplast  a biological unit consisting of a nucleus and the body of cytoplasm with which it interacts
     part:  cytoplasm  the protoplasm of a cell excluding the nucleus
        part:  microsome  a tiny granule in the cytoplasm
        part:  Golgi_body__Golgi_apparatus__Golgi_complex__dictyosome  a net-like structure in the cytoplasm of animal cells (especially in those cells that produce secretions)
     part:  cell_nucleus__nucleus__nucleu__karyon  a part of the cell containing DNA and RNA and responsible for growth and reproduction
        part:  nucleolus__nucleolu__nucleole  a small round body of protein in a cell nucleus; nucleoli contain RNA and are involved in protein synthesis
        part:  chromatin  the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins
        part:  achromatin  the part of a cell nucleus that is relatively uncolored by stains or dyes
        part:  chromosome  a threadlike body in the cell nucleus that carries the genes in a linear order
           part:  nucleolus_organizer__nucleolusorganizer__nucleolar_organizer__nucleolarorganizer  the particular part of a chromosome that is associated with a nucleolus after nuclear division
           part:  gene  a self-replicating protein molecule that occupies a fixed place on a chromosome; a unit of heredity
           part:  chromatid  one of two identical strands into which a chromosome splits during mitosis
           part:  centromere  a specialized condensed region of a chromosomes that appears during mitosis where the chromatids are held together to form an X shape
     part:  organelle__cell_organ  a specialized part of a cell; analogous to an organ
     part:  vacuole  a tiny cavity filled with fluid in the cytoplasm of a cell
  part:  body_part  any part of an organism such as an organ or extremity
     part:  corpus  the main part of an organ or other bodily structure
