Answer:
The correct answer is 128 cells
Explanation:
Given: 1 complete cell cycle takes 24 hours. It means 1 plant cell divides into 2 cells in 24 hours. Thus, number of hours in one week will be:
24 x 7 days = 168 hours, if one cell cycle takes 24 hours, then in 168 hours there will be 7 cell cycles.
So, first cell cycle will results into 2 cells and both these cells will divide and will results into 4 cells and then after third division it will 8 cells and so on..
Therefore, at the end of 7th division there will be 128 cells.
