Which type of cell is a stem cell?
A
a cell that has not specialized yet
B
a cell that has expressed its genotype
C
a cell that has specialized into a stem cell
D
a cell that has changed from a skin cell to a stem cell
Explanation: 

Detailed explanation-1: -Stem cells are the body’s raw materials-cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.

Detailed explanation-2: -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-3: -A stem cell is a cell with the unique ability to develop into specialised cell types in the body. In the future they may be used to replace cells and tissues that have been damaged or lost due to disease.

Detailed explanation-4: -Stem cells have unspecialized capability and do not have tissue-specific structures to perform specialized functions. They can give rise to specialized cells: Stem cells go through a process called differentiation and create special types of cells (muscle, nerve, skin, etc.).
