Flower Dissection and Pollination
Quiz time!
 One person per table
Dissection
 Read the procedures first please
Dissection
 Safety!
 Be careful when you’re cutting
 Only one person handling the scalpel and the flower at one time

Dissection
 Make observations of your plant
Dissection
Dissection
 Remove the petal
 Sketch the petals and measure how long
Dissection
Dissection
 Rip open the petals and expose the inside
 Observe the pistil
Dissection
Dissection
 Carefully remove one of the stamens and make observations
Dissection
Dissection
 Rip off the rest of the petals and stamens
 Make a cut at the base of the flower
 MAKE SURE YOU CUT BELOW THE BULGING PART

 Clean up
 Work on the questions at the end
Pollination
 Pollen must get from anther to stigma of a flower
 Transfer of pollen is pollination
 Pollen on its own stigma is called self-pollination
 Pollen goes from one flower to another is called cross-
pollination
Pollination
 Wind
 Some plants use wind to pollinate
 Simple, white flowers
 No scents or nectar
Pollination
 Insect, Animal, and Bird
 Plant provide food for pollinators
 Usually in form of nectar which is a liquid rich in sugar
 The VECTOR will inadvertently pick up pollen when feeding
 Goes off to feed on another flower and drop off pollen
Pollination
 BEE
 Flower has colourful petals
 Under ultraviolet lights, can see landing pattern for bees
 Usually have a landing pad for bees to safely land and feed
Pollination
 Bats
 Bats cannot see
 Flowers that use bats have no fancy colours
 Use fruity scents to attract bats
