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.
These cells are called pluripotential cells. Other, unipotential stem cells have a limited capacity for self-renewal. Also known as progenitor cells, unipotential cells become committed to forming only one type of blood cell line-erythrocytes (red blood cells), leukocytes (white blood cells), or platelets.arrow looks yellow when it holds many fat cells; it appears red when it has more blood-forming material. The marrow is the principal site for hematopoiesis (blood formation), which, after birth, occurs primarily within the bones of the legs, arms, ribs, sternum (breastbone), and vertebrae (backbones).
