A cell divides every minute. At this rate of division it can fill a 100 ml. of beaker in one hour. How much time does it take to fill a 50 ml beaker ?
- 30 minutes
- 60 minutes
- 59 minutes
- 32 minutes
The Correct Option is D
Solution and Explanation
The question is based on the concept of dividing cells, where each cell divides once per minute. If the beaker is completely filled in 60 minutes, it means that at 59 minutes, it was exactly half full. In the next minute, all the cells in the half-filled beaker divided, resulting in the beaker being completely filled by the 60th minute.

Cell Cycle and Cell Division
Cell Cycle:
The sequence of events by which a cell copies itself synthesizes other constituents of the cell and eventually splits into two daughter cells is termed the cell cycle. The cell synthesizes all its constituents in a sequential pattern to make sure the proper division and distribution of components that occurs between the two daughter cells. Therefore, we can say that the cell cycle is the period of time between the development of new daughter cells and their further division.
Stages of Cell Cycle:
The cell cycle can be sub-divided into an additional category of Interphase. Meanwhile, the Interphase can be branched into 3 further stages, such as:
- G1 Phase - “Gap 1 Phase”
- S Phase - "Synthesis Phase"
- G2 Phase - "Gap 2 Phase"

Cell Division:
The division of the parent cells into two or more cells is called daughter cell, cell division takes place. In general, it occurs as a part of a larger cell cycle. All the cell reproduces by dividing into two, wherein each parental cell produces two daughter cells.
Stages of Cell Division:
Cell division can be widely divided into several sub-segments that result from Mitosis and Meiosis.
- Mitosis or (M Phase)
- Meiosis
