  cilias, cilium WKP
  Definition: Cilia (and flagella) are microtubule-based hair-like organelles that extend from the surface of almost all cell types of the human body.
  Although these highly conserved structures are found across a broad range of species, a nearly ubiquitous appearance is observed only in vertebrates.
  Cilia can be structurally divided into subcompartments that include a basal body, transition zone, axoneme, ciliary membrane and the ciliary tip.

• nucleolus
  4 December 2003

  The nucleolus is the dense globular mass of material within the nucleus. As the cell grows, one or more nucleoli may appear. Nucleoli are sites where the RNA subunits and ribosomes are assembled. These subunits are then shipped out of the nucleus into the cytoplasm where proteins can be synthesized and the functional ribosomes can attach to the rough ER.
  Function
  assembling ribosomal subunits is well established
  processing and modification of preribosomal RNA
