Question

A bacterial cell undergoes binary fission every twenty minutes. Starting with a single bacterium how many bacteria will produce at the end of 3 hours

Answer 1

Binary fission- it means the unicellular organism divides into two identical daughter cells... that is in 20 minutes it divides into 2 equal halves.

so, 3 hours = 180 minutes and in 20 minutes they divide into 2 parts... a small math needed,

let the total number of cells at the end of 3 hours be 'x'

x= 2*180/20

x=18

thus we get 18 bacterium cells at the end of 3 hours!
