binary fission

• Binary fission is not the same as mitosis
• Binary fission occurs in eukaryotic cells like human cells.

  False
• What type of organisms undergo binary fission?

  Prokaryotic organisms
• Bacteria may have a flagellum for movement.
• All bacteria have a flagellum for movement.

  False
• What are the key structures of a bacterial cell involved in binary fission?

  DNA and plasmids
• Why is binary fission considered asexual reproduction?

  One cell splits into two
• Steps in the process of binary fission:

  1️⃣ Cell grows in size

  2️⃣ DNA replicates

  3️⃣ DNA moves to opposite sides

  4️⃣ New cell wall forms

  5️⃣ Cell divides into two
• During binary fission, plasmids are arranged randomly in the new cells.
• The new cell wall grows down the middle of the cell.
• What happens to the large circular strand of DNA during binary fission?

  Replicates and moves to opposite sides
• Binary fission can take as little as 20 minutes under optimal conditions.
• What does the term "mean division time" refer to?

  Time taken for one division
• If a bacterial cell has a mean division time of 30 minutes, it will produce 64 cells after three hours.
• How many division cycles will a bacterial cell with a mean division time of 20 minutes undergo in 4 hours?

  12 cycles
• After 4 hours, 1,000 bacteria with a mean division time of 20 minutes will produce 4,096,000 cells.
• The mean division time of bacteria depends on the species and environmental conditions.
• What conditions are optimal for bacterial growth and division?

  Warm, moist, and nutrient-rich
