Cell Differentiations the word for when cells begin to differentiate. Cell differentiation is a process in which a non-specific cell develops into a certain type of cell in response to triggers from the body or the cell. This allows single celled organisms to develop into multi-cellular organisms.
The steps in Cell Differentiation are the:
The steps in Cell Differentiation are the:
Morula stage,
the Blastula stage,
the Gastrula stage,
and the Neurula stage.
Germ Layers:
Endoderm
The endoderm produces tissues within the lungs, thyroid, and pancreas.
The endoderm is one of the germ layers formed during embryogenesis. The endoderm creates: the stomach, the colon, the liver, the pancreas, the urinary bladder, the lining of the urethra, the epithelial parts of trachea, the lungs, the pharynx, the thyroid, the parathyroid, and the intestines.
Mesoderm
The mesoderm helps in the production of cardiac muscle, skeletal muscle, smooth muscle, tissues within the kidneys, and red blood cells.
The mesoderm germ layer forms in the embryos of triploblastic animals. During gastrulation, some of the cells move inward and contribute to the mesoderm, an additional layer between the endoderm and the ectoderm.
The mesoderm creates: skeletal muscle, the skeleton, the dermis of skin, connective tissue, the urogenital system, the heart, blood (lymph cells), and the spleen.

Ectoderm
The ectoderm produces tissues within the epidermis, helps in the formation of neurons within the brain, and builds melanocytes. The ectoderm is the start of a tissue that covers the body surfaces. It emerges first and forms from the outside of the germ layers. The ectoderm makes: the central nervous system, the lens of the eye, cranial and sensory, the ganglia and nerves, pigment cells, head connective tissues, the epidermis, hair, and mammary glands.
