  • Asexual reproduction
• Types of sexual reproduction in animals

  • Fission
  • Budding
  • Fragmentation
  • Parthenogenesis
• Fission


  Asexual reproduction by a separation of the body into two new bodies
• Budding


  A form of asexual reproduction that results from the outgrowth of a part of a cell or body region leading to a separation from the original organism into two individuals
• Fragmentation


  Occurs when a parent organism breaks into fragments, or pieces, and each fragment develops into a new organism
• Parthenogenesis


  Asexual reproduction in which growth and development of an embryo occur directly from an egg, without need for fertilization
• Plants' Reproduction


  • Sexual reproduction
  • Asexual reproduction
• Plants' Asexual reproduction


  • Plant budding
  • Plant fragmentation
  • Vegetative propagation
  • Spore formation
• Plant Budding


  The mode of asexual reproduction wherein a new plant is developed from an outgrowth known as the bud
• Vegetative propagation


  Taking a part of one parent plant and causing it to regenerate itself into a new plant
• Plant Fragmentation


  Many species can also create new offspring through the growth and development of the detached fragments
• Spore Formation


  The plants produce hundreds of spores and the spore sac bursts. these spores are dispersed into the air, where they germinate and create a new plant under favorable conditions
• Do plants need to breathe?
• How do animals breathe?
• Feeding Mechanism


  • How do plants eat?
