Transcript

  • 1. How a Flower is Pollinated The purpose of all flowers is to be pollinated and produce seeds
  • 2. What do petals do?  Partly used to protect the male and female parts of the plant  Plants which use insects to transfer the pollen usually have large petals which smell and are brightly coloured
  • 3. What is the male part?  The male part of the flower is called the stamen  It has a long stalk called the filament  At the top of the filament is the anther
  • 4. What is the anther?  The anther produces pollen
  • 5. What is the female part?  Carpels are the female parts  They are made up of a stigma, style and ovary
  • 6. What is the stigma?  It is at the top of the carpel  It is sticky which helps catch pollen grains
  • 7. What are the ovaries?  The ovaries are where the eggs are made
  • 8. How does pollination take place?  Pollen grains brush against the insect, it flies to another plant, the grains rub on the stigma  The grain of pollen grows a tube, which goes down the style until it reaches the ovary  The male part joins with the female part to form a seed. This is called fertilisation.  After fertilisation the petal drop off because they are no longer needed
