Binary Fission

• Which type of organism(s) divide via binary fission?

  Bacteria 
• Is binary fission a type of mitosis, a type of meiosis, or different from either?

  Different from either
• Are bacteria eukaryotic or prokaryotic? 

  Prokaryotic
• What is the name of the tail that is on some bacterial cells?

  Flagella
• True or false? Bacteria are unicellular. This means that when they divide by binary fission they're also reproducing as each new cell is a separate organism.

  True
• When bacteria divide by binary fission, is it an example of asexual reproduction or sexual reproduction?


  Asexual reproduction
• Which two things must a bacterial cell do before it can divide?

  Grow 

  Replicate its genetic material
• Once a bacterial cell has grown and replicated its genetic material, it is ready to divide by binary fission. 

  Describe the stages of this process. 

  The two circular strands of DNA move to opposite sides of the cell

  A new cell wall forms down the middle of the cell

  The two halves pull apart to form two cells
• During binary fission, are the plasmids always split equally between the two new cells?

  No
• What is the mean division time?

  The mean (average) time it takes for a bacterial cell to divide.
• A type of bacteria have a division time of 20 minutes. If the population starts with just one cell, how many bacteria cells would be there after 1h?

  8
• Which three conditions do bacteria require for fast growth? 

  Warm

  Plenty of nutrients 

  Moist
• What is the formula for the number of divisions?

  Number of divisions = $\frac{Total\ time\ }{Division\ time}$
• What is the formula the number of bacteria?

  Number of bacteria = $2^{Number\ of\ division}$
