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.
The process by which the body produces blood is called hematopoiesis. All blood cells (RBCs, WBCs and platelets) come from the same type of cell, called the pluripotential hematopoietic stem cell. This group of cells has the potential to form any of the different types of blood cells and also to reproduce itself.This cell then forms committed stem cells that will form specific types of blood cells. Red blood cells (RBCs), also known as erythrocytes, are by far the most abundant cells in the blood.his group of cells has the potential to form any of the different types of blood cells and also to reproduce itself.
