Final answer:
Most adult cells are incapable of undergoing cell division after being differentiated.
Step-by-step explanation:
After being differentiated, most adult cells are incapable of undergoing cell division.
Cell differentiation is the process by which unspecialized cells become specialized to carry out distinct functions. When a cell differentiates, it undergoes major changes in size, shape, metabolic activity, and overall function.
Once a cell has fully differentiated, it typically loses the ability to divide or replicate.
For example, red blood cells are terminally differentiated cells that have a finite lifespan and cannot undergo cell division. They are regularly replaced by stem cells.
