Detailed explanation-1: -Stem cells are different from other cells in the body in three ways: They can divide and renew themselves over a long time. They are unspecialized, so they cannot do specific functions in the body. They have the potential to become specialized cells, such as muscle cells, blood cells, and brain cells.

Detailed explanation-2: -Furthermore, whereas animal stem cells are in general responsible for maintaining a specific tissue, plant stem cells generate complete organs, and as such resemble animal pluripotent embryonic stem (ES) cells.
