    sepals.
  • What is the female part of the flower called?
    The carpel or the pistil.
  • Name two ways that flowers are pollinated.
    Birds, insects, wind
  • What is germination?
    This is when a seed first starts to grow.
  • Name the part of the flower that attracts insects and birds.
    petals.
  • Name the part of the flower that makes pollen.
    anthers.
  • Why does the seed need a food store?
    So that the embryo can get energy to grow into a new plant.
  • How does a spongy seed coat help the water lily to disperse its seeds?
    The spongy coat has air spaces that trap air and help the seeds to float.
  • How is this seed suited to its method of dispersal?
    This seed has hooks to stick to animals' fur.
  • What do seeds need to germinate?
    They need water, warmth and air to germinate.
  • What is the male part of the flower called?
    The stamen.
  • Put the life cycle in the correct order: fertilisation; germination; growth; seed dispersal; pollination; seed production
    germination-growth-pollination-fertilisation-seed production-seed dispersal
  • What do plants need to grow?
    Plants need light, air, water, and warmth to grow.
  • Which part of the new bean plant grows first?
    The first root is the first part to grow.
  • Name a possible factor that this plant is missing to grow.
    Light or water.
  • Name the part of the flower that contains eggs.
    ovary.
  • How is this flower pollinated? Give a reason for your answer.
    Insects / Birds. It has brightly coloured petals.
  • How does pollination help the plant reproduce?
    Pollination brings the male pollen to the female stigma so that fertilisation can take place to form seeds.
  • How is pollination different to fertilisation?
    Pollination is when pollen is carried from the stamens to the stigma of a flower. Fertilisation is when the pollen and egg cells join together in the ovary.
  • How is the bush willow seed dispersed? Give a reason for your answer.
    By wind. It has papery wings.
  • Name three ways that seeds are dispersed.
    wind, water, animals, explosion
