Binary fission

• What is binary vision?

  Process by which prokaryotic organisms divide
• How does binary fission differ from mitosis?

  Binary fission occurs in prokaryotic cells
• What type of organisms undergo binary fission?

  Prokaryotic organisms like bacteria
• What structures do bacterial cells have?

  Cell wall, cell membrane, cytoplasm, DNA
• What is the function of plasmids in bacteria?

  Contain non-essential genes
• What is a flagellum?

  A tail used for movement in bacteria
• Why is binary fission considered a type of reproduction?

  It divides one organism into two organisms
• What are the two main steps before binary fission occurs?

  Growth and replication of genetic material
• How often can some bacteria divide under optimal conditions?

  Every 20 minutes
• If a bacterial cell divides every 20 minutes, how many cells will there be after 5 hours?

  Over 250,000 bacteria
• What is mean division time?

  Average time it takes for a cell to divide
• How many division cycles occur in 3 hours if the mean division time is 30 minutes?

  6 division cycles
• How many cells are produced after 3 hours from one bacterial cell with a mean division time of 30 minutes?

  64 cells
• What factors affect the mean division time of bacteria?

  Species and environmental conditions
• How many division cycles occur in 4 hours if the division time is 20 minutes?

  12 division cycles
• How many cells will there be after 4 hours from 1,000 bacteria dividing every 20 minutes?

  4,096,000 cells
• What is the process of binary fission in bacteria?

  1. Bacterial cell grows larger
  2. Replicates its DNA and plasmids
  3. DNA strands move to opposite sides
  4. New cell wall forms down the middle
  5. Cell divides into two new bacterial cells
• What are the optimal conditions for bacterial growth?

  • Warm temperature
  • Moist environment
  • Plenty of nutrients
• What is the significance of binary fission in bacterial populations?

  • Rapid population growth
  • Asexual reproduction method
  • Essential for survival and adaptation
