POLLINATION

 WHAT IS POLLINATION 

- POLLINATION is the transfer of pollen grains from the anther to the stigma of the same or different flowers.  Pollination can be done by insects or wind 

THE ARE TWO TYPES OF POLLINATION 

1. Self-pollination.                                                               - This occurs when a pollen grain lands on the stigma of the same flower or flower of the same plant.

2. Cross Pollination.                                                            - This occurs when a pollen grain lands on the stigma of a flower of a different plant of the sabe species.

THE DIFFERENCE BETWEEN INSECT AND WIND POLLINATED FLOWERS 

Insect pollinated.                          Wind pollinated 

▪︎ Large flower.                              ▪︎ Small flower 

▪︎ Bright petals.                              ▪︎ Dull color petals

▪︎ Scented petals.                           ▪︎ No scent

▪︎ Nectar present.                          ▪︎ No nectar 

MECHANISM OF POLLINATION IN MAIZE PLANT🌽  ( Wind Pollination)

-A maize plant has no petals.                                          - Therefore it cannot attract insects to itself for pollination.                                                                          - The structure of a maize flower (tassel) and cob is adapted for wind pollination e.g. pollen grains is light and powdery  and can therefore be carried by wind.                                                                                    - Style can easily trap pollen because they are long and sticky. 

MECHANISM OF POLLINATION ON BEANS PLANT 🫘 ( Insect Pollination)

-When insect lands on the flower to collect nectar , pollen sticks to the hair of an insect.                             -When it visits another bean flower the pollen is dropped/left on the stigma of that flower 🌼 .
