NEET2009BotanyCell Cycle and Cell DivisionActual
A bacterium divides every 35 minutes. If a culture containing (10^5 ) cells (/ ml ) is grown in 175 minutes, what will be cell concentration after that period
Options
- A(35 10^5 )
- B(5 10^5 )
- C(32 10^5 )
- D(175 10^5 )
Correct answer
D. (175 10^5 )
Step-by-step solution
As we know that bacterium divided after every 35 minutes through simple mitotic division therefore, number of divisions are 175 35 =5 Since, one bacterium on division produces two cells so, cell concentration after 175 minutes will be aligned & =10^5 (2)^5 & =32 10^5 aligned
