Expert Answer:

Cells are not only characterized by their genetic material and other interior components, but also by the genes they express. Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. For example, melanocytes in the skin are highly specialized cells which mostly make the pigment melanin. Plasma cells on the other are highly specialised for making antibodies. It is due to the regulation of genes that although all the cells of a multicellular organism have the same genetic constitution yet they perform different functions.
