Parts of Reproduction

• Sexual Reproduction


  • Involves 2 parents
  • Offspring inherit half of their trait information from one parent, and half from the other, making the offspring genetically distinct
• Asexual Reproduction


  • Only requires one parent
  • Trait information from the parent is passed down to the offspring
  • The offspring is therefore an exact copy of the parent
• Internal Fertilization


  Occurs inside the organism's body
• External Fertilization


  Occurs outside the organism's body
• Binary Fission


  An organism divides into two, each half develops into a new organism
• Budding


  A tiny bud grows on some parts of the parent organism's body, falls off and becomes an independent organism
• Fragmentation and Regeneration


  Separated pieces of the parent organism can develop into a whole individual
• Petal


  Their vibrant colors and alluring scents are nature's way of attracting pollinators like bees, butterflies, and birds
• Sepal


  • Typically green in color and located at the base of the flower
  • Encloses the developing bud
• Stamen


  • It is the male reproductive organ of a flower, typically consisting of an anther and a filament
  • Anther is where pollen grains are produced and stored
  • Filament supports the anther
• Pistil


  • It is the female reproductive organ found in the center of a flower
  • Stigma is the sticky surface at the top of the pistil where pollen is received
  • Style is the tube-like structure that connects the stigma to the ovary
  • Ovary is the swollen base of the pistil that contains the ovule, which develop into seeds once fertilized
• Pollination


  Refers to the transfer of pollen grains from anther to stigma
• Stages of Sexual Reproduction in Plants

  • Pollination
  • Fertilization
  • Seed Dispersal
  • Germination
• Runners


  New plants arise from the nodes of a horizontal stem above the ground
• Tubers


  Swollen, underground stem that stores food and forms a new plant
• Bulbs


  Short underground stems that has fleshy leaves that stores food
• Rhizome


  Horizontal underground plant stem capable of producing the shoot and root systems of a new plant
