Presentation Transcript

  1. Asexual Reproduction

  2. Sea Star

  3. If asexual reproduction involves mitosis, how would the parent cell compare to the daughter cell?

  4. Asexual Reproduction • Asexual reproduction = cloning • Involves only one parent • Parent and offspring are identical (DNA is exactly the same) • Asexual reproduction involves mitotic cell division

  5. Types of Asexual Reproduction • Binary fission • Budding • Regeneration • Sporulation

  6. Binary Fission

  7. Binary (2) Fission (cut) Mitotic cell division with EQUAL cytoplasmic division Ameba, bacteria, and paramecium reproduce by binary fission Binary Fission

  8. Budding

  9. Budding • Mitotic cell division but UNEQUAL cytoplasmic division • Yeast and hydra reproduce by budding • Example:

  10. Regeneration

  11. Regeneration • Ability of an organism to grow back a lost part by mitotic cell division • Starfish and flat worms have the ability to regenerate. • They are invertebrates • Large areas of undifferentiated tissues

  12. Sporulation • Parent cell produces specialized cells (spores) by mitosis • Large numbers of offspring are produced and released at one time • Bread mold reproduces by sporulation
