Detailed explanation-1: -Stem cells are self-renewing, undifferentiated cells that divide by mitosis to produce specific body cell types. There are two broad types of stem cells, namely, adult and embryonic.
Detailed explanation-2: -When a cell undergoes mitosis, it duplicates its DNA and separates into two new cells that have the same genetic code. They are two identical copies (or daughter cells) from one mother cell. These daughter cells can either remain as stem cells or differentiate into specialised cell types.
Detailed explanation-3: -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-4: -All stem cells-regardless of their source-have three special properties: 1. Stem cells are unspecialized. A stem cell does not have any tissue-specific structures that allow it to perform specialized functions.
