Cell differentiation is the process in which specialized cells are formed from totipotent cells. Totipotent cells are present in the zygote and they have the ability to develop into any type of cells. They can even differentiate to extra-embryonic membranes and placenta.

Stem cells are unspecialized cells from which different kinds of specialized cells can develop. We differ embryonic and adult type. Embryonic stem cells are pluripotent, which means that they have the ability to develop into any cell type in the body. However, adult stem cells are multipotent, which means that they can differentiate into several types of specialized cells.

Cell differentiation is the process in which specialized cells are formed from totipotent cells. Totipotent cells are present in the zygote and they have the ability to develop into any type of cells. They can even differentiate to extra-embryonic membranes and placenta. This process is important because multicellular organisms are made of cells specialized for various functions.
