1. Cell Division - Amoebas

• Asexual Reproduction Mitosis
• Amoeba unicellular protozoan
• Every three days grows large enough to divide
• No shape to star shape to long and thin shape
  to two no shape cells

2. Budding

• Asexual Reproduction
• Occurs in yeast cells
• Mitosis, yet instead of cell dividing, new
  nucleus goes into a bulge (bud)
• Sometimes bud may break off, but usually
  continues budding process and forms a long chain
  of yeast cells

3. Regeneration

• Regeneration asexual reproduction by the
  process of regrowing missing body parts
• Example Planarian (flat worm)cut into pieces
  and each piece will grow missing parts until it
  becomes a whole planarian.
• Regeneration can be repair or replacement vs
  reproduction
• Example deer growing new antlers or a lizard
  growing a new tail

4. Spores

• Spore a cell surrounded by a protective
  covering
• Asexual reproduction - one cell can produce many
  spores and each can grow into a new organism
• Protective covering helps them live in
  unfavorable conditions
• Example bread mold

5. Mitosis vs. Meiosis

• A. Mitosis- one organism - cell duplicates genes
  cell divides asexual reproduction
• B. Meiosis two organisms - each gives a
  complete copy of genes to form a new organism
