Asexual Reproduction

1
Asexual Reproduction

• Bacteria, Protists, Fungi and Animals

What is Asexual Reproduction?

• The formation of a new individual from a single
  organism.
• Has identical genetic information as its parent.
• Yes, thats right. These organisms can reproduce
  all on their own, they never need to find a
  partner!

Binary Fission

• Parent cell divides so that each new cell
  contains a single chromosome carrying a complete
  set of DNA identical to its parents
• First it copies its single chromosome, then
  divides into two new identical cells.

• This happens for some organisms like mushrooms
  and corals.
• A small piece or fragment breaks away from the
  main mass and grows into a new individual.

Budding

• A copy is made of the nucleus, next a tiny bud
  begins to form on the cell wall.
• The bud contains the new nucleus and continues to
  grow larger.
• Eventually it breaks away to become a new
  independent cell.
• Happens in yeast

8
Spores

• A reproductive cell that can grow into a new
  individual through mitotic cell division.
• Spores are stored in a case called a sporangium.
• Ferns reproduce this way.

Regeneration

• These organisms reproduce by dividing in two and
  regenerating the parts they are missing.
• Planaria worms and sea stars can do this. Its
  really strange
