bacterial division

• How do bacteria reproduce?

  By binary fission
• What happens during binary fission in bacteria?

  One cell splits into two identical cells
• What is involved in the binary fission process?

  Replication of bacterial DNA and cytoplasm division
• What conditions are required for bacterial growth and division?

  • Warmth
  • Moisture
  • Nutrients
• How quickly can bacteria double under ideal conditions?

  Approximately every 20 minutes
• What is exponential growth in bacteria?

  Rapid increase in population size
• What formula is used to calculate the number of bacteria after a certain time?

  Number of bacteria = Initial number × 2^{number of divisions}
• If you start with 1 bacterium and it divides every 20 minutes, how many bacteria will there be after 1 hour?

  8 bacteria
• How do you calculate the number of bacteria after 3 divisions if starting with 1 bacterium?

  1 × 2^3 = 8 bacteria
