The approximate number of differentiated cell types in a human body is
A) 10.
B) 100.

D) 840.
E) 3.2 billion.

Accepted Answer

It is estimated that there are around 260 differentiated cell types in the human body, ranging from skin cells to blood cells to nerve cells. However, the exact number may be difficult to determine as new cell types are still being discovered and classified. Options A, B, and D are too low, while option E is too high, as it is much greater than the estimated number of human cells in the body.
