Explanation:
Detailed explanation-1: -Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and repair body tissues.
Detailed explanation-2: -What is the reason a stem cell can differentiate into many other types of cells, such as blood cells, nervous cells, and fat cells? Different sections of DNA get turned on depending on the type of cell needed.
