Hello students, our next topic for the MCQ is ‘STEM CELLS’. All the cells in our body are for specific function like blood cell will be only blood cell, nerve cell will be only nerve cell and it will not become muscle cell or any other cell in the body. But the stem cells have ability to become any type of cell because they are not specialized for the specific function. The stem cells are of two types i.e. the embryonic and adult stem cells.
The MCQ will give you more information about stem cells.
