How does the Cnidocyte of a Cnidarian Function? A cnidocyte, cnidoblast or nematocyte, is a type of venomous cell unique to the phylum Cnidaria (corals, sea anemones, hydrae, jellyfish, etc.).
Such cells are called stem cells. Stem cells are those undifferentiated cells which have the potential to become specialized to form a specific type of cell. For instance, mesenchymal stem cells are a type of stem cells which can differentiate into osteoblasts, chrondocytes, myocytes and adipocytes.
What name is given to the process that is responsible for this? At one point, you were just an undifferentiated, single cell. You are now made of many cells; some of these cells function as liver cells, some as muscle cells, some as red blood cells, while others play different roles.
