Binary fission

Cards (23)

  • What is binary vision primarily about?
    Binary vision is about binary fission.
  • What type of organisms undergo binary fission?
    Prokaryotic organisms like bacteria
  • How does binary fission differ from mitosis and meiosis?
    Binary fission occurs in prokaryotic cells.
  • What structures do bacterial cells have?
    Cell wall, cell membrane, cytoplasm, DNA
  • What is the function of plasmids in bacteria?
    Plasmids contain non-essential genes.
  • What is a flagellum in bacteria?
    A tail used for movement.
  • 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.
  • What happens to the large circular DNA during binary fission?
    It moves to either side of the cell.
  • How are plasmids distributed during binary fission?
    They are arranged randomly between offspring cells.
  • What forms down the middle of the cell during binary fission?
    A new cell wall grows down the middle.
  • How quickly can some bacteria divide under optimal conditions?
    Every 20 minutes.
  • What happens to the bacterial population with each division?
    The population doubles with each division.
  • How many bacteria are there after 5 hours if they double every 20 minutes?
    Over 250,000 bacteria.
  • How do you calculate the number of division cycles in three hours?
    Divide 180 minutes by mean division time.
  • If a bacterial cell divides every 30 minutes, how many cells after three hours?
    64 cells after three hours.
  • What does mean division time refer to?
    Average time it takes to divide.
  • What factors affect the mean division time of bacteria?
    Species and environmental conditions.
  • How many division cycles in four hours if division time is 20 minutes?
    12 division cycles.
  • How many cells are there after four hours starting with 1,000 bacteria?
    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 temperatures
    • Moist environments
    • Plenty of nutrients
  • What is the significance of binary fission in bacterial reproduction?
    • It allows rapid population growth.
    • It is a form of asexual reproduction.
    • It enables survival in favorable conditions.
