What is a stem cell?
A
a cell that has a stem
B
an unspecialized cells from which differentiated cells develop
C
cells that are found in plant stem
D
cells that are found in bacteria only
Explanation: 

Detailed explanation-1: -Stem cells are unspecialized cells of the human body. They are able to differentiate into any cell of an organism and have the ability of self-renewal. Stem cells exist both in embryos and adult cells. There are several steps of specialization.

Detailed explanation-2: -Stem cells are unspecialized cells from which differentiated cells develop. There are two types of stem cells: embryonic and adult stem cells. Embryonic stem cells are found in the inner cell mass of the blastocyst. Embryonic stem cells are pluripotent and capable of almost indefinite regeneration.

Detailed explanation-3: -Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells.

Detailed explanation-4: -Sometimes called the body’s “master cells, ” stem cells are the cells that develop into blood, brain, bones, and all of the body’s organs. They have the potential to repair, restore, replace, and regenerate cells, and could possibly be used to treat many medical conditions and diseases.

Detailed explanation-5: -Stem cells are unspecialized. A stem cell does not have any tissue-specific structures that allow it to perform specialized functions.
