binary fission

Question 1

How do prokaryotic cells reproduce?

Answer 1

cell divide called binary fission

Question 2

how does binary fission happen?

Answer 2

1- circular DNA replicates
2- cell gets bigger and DNA moves to opposite sides
3- cytoplasm divides and new cell walls begin to form

Question 3

how does bacteria cells divide

Answer 3

with the right conditions - warm environment and lots of nutrients

Question 4

what happens when the bacteria cell doesn’t have right conditions?

Answer 4

they will eventually begin to die

Question 5

what is mean division time?

Answer 5

the average rime is takes a bacteria cell to divide into two

Question 6

how to calculate mean division?

Answer 6

A bacteria cell has a mean division time of 30 minutes.
How many cells will in produce after 2.5 hours?

convert the hours to minute - 2.5 x 60 = 150 minutes

divide the new number with the divide time
150 mins divided by 30 mins = 5 divisions

each cell divides to produce 2 cells, so the number pf cells increase by a power of 2 for each division
-5 divisions-
2x2x2x2x2= 32 cells formed s
