You should include:

Explanations of:
  • Pollination
    • A labelled diagram showing the parts of a flower
    • Explain how this happens in words
    • See if you can find a GOOD video on Youtube that explains how pollination happens
    • Include the following words: wind, animal, pollen, stigma, anther, flower, colour, scent, petal and nectar.
    • Pictures of flowers that are pollinated by both the wind and animals. You should also explain the differences between the two types of flower.
The petals


pollen_1.jpgThis is a wind pollinated plant. pollen_2.jpgThis is a insect, bird pollenated plant.


  • Fertilisation
    • Explain how this happens in words
    • See if you can find a GOOD video on Youtube that explains how fertisation creates seeds.
    • Include the following words: Pollen, pollen tube, stigma, style, ovary, ova, fertililise, and seed.

  • Seed dispersal
    • Explain why plants disprese their seeds around rather than allowing them to drop on the floor around them.
    Because if all the seeds grow right next to the plant they will have to fight for the sun rays for photosynthesis.
    • Give examples of different ways that different plants disperse their seeds
    Beans expload when they get to big, and blueberries get animals and birds to eat them so when they excrete it grows from where they excrete .
    • State the conditions seeds require before they germinate

Pollination -

Pollination is the transfer of pollen grains from the anther of one flower to the stigma of the other. It may happen when an insect such as a bee goes from flower to flower. Pollen sticks to the bee and gets carried from one flower to the next and ends on the stigma. Pollination can also happen when wind blows pollen about and gets caught on the stigma.


Fertilisation -

Fertilisation happens when the nucleus of the male sex cell (pollen grains) joins with nucleus of the female sex cell (egg cell) . In plants, fertilisation happens after pollination. The nucleus of the pollen grain and the nucleus of the egg cell join to produce a fertilised egg cell.
