Asexual vs sexual reproduction mod

  1. 1. Asexual vs. Sexual Reproduction<br />1<br />
  2. 2. Types of Asexual Reproduction <br />Binary fission<br />Budding<br />Fragmentation<br />Vegetative propagation<br />Parthenogenesis<br />2<br />
  3. 3. What is asexual reproduction?<br />Requires only one parent<br />Offspring have 100% the same chromosomes as the parent.<br />In other words, the offspring are exact “clones” of the parent.<br />Mitosis<br />Movie<br />3<br />
  4. 4. Asexual Reproduction<br />Binary Fission<br />Bacteria<br />Protists<br />4<br />Binary fission is a form of asexual reproduction where every organelle is copied and the organism divides in two.<br />
  5. 5. Asexual Reproduction<br />Budding<br />Hydra<br />Movie<br />Yeast<br />5<br />Budding is a means of asexual reproduction whereby a new individual develops from an outgrowth of a parent, splits off, and lives independently.<br />Yeast<br />
  6. 6. Asexual Reproduction<br />Fragmentation<br />Sea stars<br />flatworms<br />6<br />Fragmentation is a means of asexual reproduction whereby a single parent breaks into parts that regenerate into whole new individuals.<br />
  7. 7. Asexual Reproduction<br />Vegetative Propagation<br />7<br /><ul><li>Bulbs, tubers and suckers are underground structures that can grow to form new plants, eg tulips, potatoes, bananas
  8. 8. Runners are fast growing stems that grow along the surface of the soil and take root. Eg strawberries
  9. 9. Some plants can grow from cuttings of roots, stems, and leaves.</li></li></ul><li>Asexual Reproduction<br />Parthenogenesis<br />Females reproduce without fertilisation by males<br />Found in both invertebrates and vertebrates<br />8<br />
  10. 10. Sexual Reproduction<br />Requires special sex cells called gametes from two parents<br />Gametes are formed by the process of Meiosis – which results in a cell with half of the genetic material of the parent<br />each cell only contains half of the genetic material needed, two cells must fuse to provide the correct amount of DNA<br />Offspring have characteristics of each parent<br />9<br />
  11. 11. Sexual Reproduction <br />Fertilisation<br />When the gametes of the two parents fuse to produce a zygote<br />10<br />
