Detailed explanation-1: -If cell divisions are not followed by cell differentiation in a developing embryo, it will grow into a mass of cells without the formation of tissues or organ systems. The embryo would not grow into a fully developed organism.
Detailed explanation-2: -In the adult, however, the replacement of shed or worn out cells takes place by division of somatic stem cells (also called adult stem cells), which are not fully differentiated, but can give rise to only a limited array of cells.
Detailed explanation-3: -Stem cells are cells that are not differentiated and can become many different types of cells. There are embryonic stem cells that occur during human development, but there are also adult stem cells that are situated to replace specific types of tissue in the adult body.
