  • 1. Flower Dissection Activity Review
  • 2. Flowering Plants
    • A flowering plant has both male and female parts.
    The male part is called the stamen . The female part is called the pistil .
  • 3.
    • Stamen: The male reproductive structure of a flowering plant
  • 4.
    • Anther: the structure located on top of the stamen and carries the pollen
  • 5. Pollen
    • Pollen is the male sex cell that donates half of the DNA to make a seed.
    It is a powdery substance, usually orange or yellow in color, that gets carried by pollinators.
  • 6.
    • Filament: a thread-like part that holds up the anther
  • 7.
    • Pistil: the female reproductive structure of a flowering plant
  • 8.
    • Stigma: the sticky surface on the top of the pistil; it traps and holds the pollen
  • 9.
    • Style: the tube-like structure that holds up the stigma
  • 10.
    • Ovary: the plant part at the bottom of the flower that has ovules inside (this turns into the fruit and seeds we eat)
  • 11.
    • Ovules: the female sex cells inside the ovary that donate half the DNA to become the seed
    • (They become the seeds when pollinated or fertilized by the pollen.)
    A baby seed! 
  • 12. Petal: the colorful flower parts that surround the reproductive structures
  • 13.
    • Sepal: the green petal-like parts at the base of the flower; they help protect the bud when it develops
  • 14.
    • Perfect: flowers that have both male and female parts (ex. Roses, lilies, and pea plants)
  • 15.
    • Imperfect: flowers with male or female parts (ex- cucumbers, pumpkins, and melons)
  • 16.
    • Pollination: when pollen moves from the male parts to the female parts
    • Pollination is the step before fertilisation in plants. Fertilisation is when the male and female gametes join to form an embryo.
