Quizplus · Accepted Answer

Some specific cells throughout the body, such as skin, stomach lining, and blood cells, retain the ability to divide and replace themselves even in adults. This is necessary for tissue repair and maintenance. Other cells, such as nerve cells, do not divide after maturity. Therefore, option A and E are false. Option B is also false as cell division in adults is normal and necessary for maintaining healthy tissues. Option D is partially true as growth in the sense of an increase in size does stop after maturity, but growth in the sense of tissue repair and renewal through cell division continues.
