  • What is the first stage of a flowering plant's life cycle?
    Flower
    Seed
    Fruit
    Root
  • Why do wind-pollinated flowers produce large amounts of pollen?
    To increase chances of pollination
    To attract insects
    To protect seeds
  • What is seed dispersal?
    Spreading seeds away from the parent plant
    Seed germination
    Flower opening
    Pollen transfer
  • Which flowers usually have light, smooth pollen that can be blown away?
    Insect-pollinated flowers
    Wind-pollinated flowers
  • What do leaves mainly do?
    Make food by photosynthesis
    Make seeds
    Disperse pollen
  • What happens when a seed germinates?
    A seedling grows
    A flower forms
    Pollen is released
    Seeds fall
  • After pollination, what forms?
    Stamen
    Petal
    Fruit
  • Which flowers usually have bright, colourful petals?
    Spore-bearing plants
    Cone-bearing plants
    Insect-pollinated flowers
    Wind-pollinated flowers
  • Seeds with hooks or spines are dispersed by:
    Wind
    Water
    Explosion
    Animals
  • What is the function of the anther?
    Hold the flower
    Produce pollen
    Disperse seeds
  • Which group includes plants like ferns and mosses?
    Non-flowering plants
    Flowering plants
  • Fruits that are eaten by animals help disperse seeds through:
    Spores
    Droppings
    Roots
  • Which part of the seed protects the seed?
    Embryo
    Cotyledon
    Seed coat
  • Which feature belongs to wind-pollinated flowers?
    Strong scent
    Large colourful petals
    Long feathery stigma
    Sticky pollen
  • What do roots mainly do?
    Make seeds
    Produce pollen
    Attract insects
    Absorb water and minerals
  • When seed pods burst open and scatter seeds, it is:
    Water dispersal
    Animal dispersal
    Wind dispersal
    Explosion dispersal
  • What is germination?
    When fruit drops
    When pollen is transferred
    When a seed starts to grow
  • Why do insect-pollinated flowers produce sticky pollen?
    To attach to insects
    To float in the air
    To stay inside the ovary

  • Which type of flower often has a strong scent to attract pollinators?
    Insect-pollinated flowers
    Wind-pollinated flowers
  • What is the function of the petals?
    Attract insects
    Produce pollen
    Spread seeds
    Protect the ovary
  • Seeds with "wings" are usually dispersed by:
    Water
    Wind
    Explosion
    Animals
  • What is pollination?
