When a single cell undergoes mitosis, it divides into two daughter cells. If each of the two initial cells undergoes three rounds of mitosis, we can calculate the total number of cells as follows:
-
After the first round of mitosis, each cell divides into 2 cells:
- 2 cells become 2 × 2 = 4 cells.
-
After the second round of mitosis, those 4 cells each divide:
- 4 cells become 4 × 2 = 8 cells.
-
After the third round of mitosis, those 8 cells each divide:
- 8 cells become 8 × 2 = 16 cells.
So, if two cells each underwent three rounds of mitosis, the total would be 16 cells.
The correct answer is 16.
