It is true that uni-potent stem cells can only produce cells that are like themselves
Answer: Option B
<u>Explanation:</u>
Uni potent cell as their name suggests can only produce cells that are just like themselves. Compared to the other stem cells that undergo proliferation this produces a tissue of that particular type alone.
Though it can’t be of much use like other cells giving rise to different cell types this is confined to the generation of one particular tissue. The uni-potent cells help to renovate and recreate themselves too. Hence any damaged tissue can be replaced by the uni-potent cell giving rise to the same tissue in case of burns etc.
