In developmental biology, cellular differentiation is the process where a cell changes from one cell type to another. Most commonly this is a less specialized type becoming a more specialized type, such as during cell growth. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.
Differentiation. Differentiation differentiation: When an unspecialised cell becomes a more specialised cell type. is the process of cells becoming specialised. Most types of animal cells differentiate at an early stage. They become specialised for a particular function and cannot change into different types of cells. In mature animals, cell division is mainly restricted to replacement and repair. On the other hand, many plant cells keep the ability to differentiate.
