  1. Chapter 3 Section 3: Asexual and Sexual Reproduction • Objectives: • 1. Explain how some organisms use cell division to reproduce asexually. • 2. Compare asexual and sexual reproduction • 3. Draw conclusions about regeneration

  2. Asexual Reproduction • In asexual reproduction, one organism produces one or more new organisms that are identical to itself and live independently. • The organism that produces the new organism(s) is the parent. • Each new organism is the offspring • The offspring are genetically identical to the parent

  3. Types of Asexual Reproduction • There are several types of asexual reproduction. • 1. Binary Fission • 2. Budding • 3. Regeneration

  4. Binary Fission • Binary fission is a form of asexual reproduction that occurs in prokaryotes. • The parent organism splits in two, producing two daughter cells. • The daughter cells are genetically identical to the parent.

  5. Budding • Unicellular & Multicellularorganisms can reproduce by budding. • Budding is a process in which an organism forms tiny buds on its body. • Each bud forms from the parents cells. • The bud grows until it forms a completely new organism that is identical to the parent.

  6. Regeneration • Regeneration is the renewal, re-growth, or restoration of a tissue, body part, or body. • In some organisms, such as starfish, a lost limb my re-grow into a whole new starfish.

  7. Sexual Reproduction • Sexual Reproduction involves two parents. • Rate of reproduction is slower than asexual reproduction • Offspring have genetic information from both parents.
