Introduction
3
Pollination

• Flowering plants use the wind, insects, bats,
  birds and mammals to transfer pollen from the
  male (stamen) part of the flower to the female
  (stigma) part of the flower.

• When bees and butterflies gather, pollen sticks
  to their bodies. As they move from flower to
  flower, they may brush against the pistils.

4
The parts of a Flower

• Sepals protect the bud until it opens.
• Petals attract insects.
• Stamens make pollen.
• Ovaries grow into fruits which contain the seeds.

5
Stamen (male)

• Anther pollen grains grow in the anther.
• When the grains are fully grown, the anther
  splits open.

6
Pistil (female)

• Stigma
• Style
• Ovaries
• Ovules (eggs)

More About Pollination

• A flower is pollinated when a pollen grain lands
  on its stigma.
• Each ovary grows into a fruit which contains the
  seeds.

11
Answer the following Questions in your Notebook

• What is pollination?
• How do insects aide pollination?
• Describe the relationship of the pistil, ovary,
  and ovules in a flower.

12
Seed dispersal

• Seeds are dispersed in many different ways
• Wind
• Explosion
• Water
• Animals
• Birds
• Scatter
• Man

13
Wind pollination

• Some flowers, such as grasses, do not have
  brightly coloured petals and nectar to attract
  insects.
• They do have stamens and carpels.
• These flowers are pollinated by the wind.
