Questions and Answers

Which type of asexual reproduction involves an organism breaking into pieces, each of which can develop into a new organism?

  • Budding
  • Regeneration
  • Fragmentation (correct)
  • Binary Fission

    • What distinguishes sexual reproduction from asexual reproduction?

  • Involves genetic information from two parents (correct)
  • Involves the division of a single organism
  • Involves the regrowth of body parts from a part of the parent
  • Produces identical offspring to the parent organism

    • In budding, what happens to the new organism during the process?

  • It divides immediately into two identical organisms
  • It requires fertilization from another organism
  • It independently breaks away without a connection to the parent
  • It grows directly from the parent until detachment (correct)

    • Which process allows an organism to regrow lost parts, such as limbs or tails?

    Study Notes

    Types of Asexual Reproduction

    • Budding: A new organism grows from a small part of the parent body, which then detaches to form a new organism.
    • Binary Fission: The parent organism duplicates its DNA and then divides into two identical organisms.
    • Fragmentation: The parent organism breaks into several fragments, each fragment grows into a new organism.
    • Spore Formation: Spores are produced by the parent organism and germinate to develop into new organisms.
