  1. Chapter 31.7 Asexual Reproduction of Flowering Plants AP Biology Spring 2011

  2. Asexual Reproduction in Nature Many plants can reproduce asexually by vegetative growth including shoots and runners

  3. Asexual Reproduction in Nature In this mode of reproduction, all of the plants produced are genetically identical clones

  4. Asexual Reproduction in Nature Examples of this form of growth include quaking aspen in Colorado, which stretch across hundreds of acres, and 11,700 year old creosote bushes in the Mojave Desert

  5. Asexual Reproduction in Nature • Strawberry plants send out runners • Oranges come from trees that reproduce by parthenogenesis • Parthenogenesis: development of an embryo from an unfertilized egg

  6. Induced Propagation Vegetative propagation (cuttings) can result in new plants produced from leaves that form roots

  7. Induced Propagation Tissue culture propagation can result in whole plants produced from a group of cells This technique is used today to produce crops that have desirable characteristics such as disease resistance, and to increase production of hybrid orchids, lilies, and other prized ornamental plants
