Explanation:
Detailed explanation-1: -Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions. A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Detailed explanation-2: -Differentiation dramatically changes a cell’s size, shape, membrane potential, metabolic activity, and responsiveness to signals. These changes are largely due to highly controlled modifications in gene expression and are the study of epigenetics.
