ALL ABOUT BINARY FISSION

  • Binary fission is reproduction when a single celled bacteria splits into 2 different bacteria
  • Binary fission is asexual reproduction

3.

THE STEPS OF BACTERIA REPRODUCTION

  • A cell copies it's chromosomes (We'll learn about that later)
  • The cell's membrane starts to grow inward
  • A new cell wall forms and separates the two new halves
