BIOL - Cell Differentiation and Stem Cells
Biology, cell differentiation, stem cell - IGCSE | IBDP | DSE | GCE | IAL | AP Biology
Multicellular organisms begin as a single cell in the form of a zygote. The zygote develops into an embryo through mitosis. The cells in the embryo also start to differentiate, that is, the cells develop features that enable them to perform specific functions and become specialized cells.
Cells that have not yet differentiated are called stem cells. In other words, stem cells have the potential to differentiate into different types of cells. Stem cells can differentiate into cells with different functions such as muscle cells, blood cells, nerve cells, or cardiac cells.
There are two types of stem cells:
