Cell division is the process by which a parent cell divides into two or more daughter cells.

Generation time is 1 minute means after every min. The cell is going to be double of its initial value.

In 20 mins culture tube ->1/8 filled

Means after 1 min it will be doubled so in 21-minute culture tube will be 1/8 *2 = 1/4 quarterly filled

Again after 1 min. It will be 1/4 *2=1/2 half filled

Again after 1 min, it will be1/2*2 = 1 (fully filled)

means in 23 minutes vessel will be completely filled.

So, the correct answer is '23 minutes'.
