PowerPoint on Pollination

1. Pollination

3. What is pollination?
This is the transfer of pollen from stamen to stigma.
Pollen grains are transferred or carried by insects, wind
or water to another flower.

4. Transfer of pollen grains

5. Types of Pollination
• Cross pollination- the transfer of pollen from the male
reproductive organ (anther) of one plant to the female
reproductive organ (stigma) of another plant.
• Self pollination- the transfer of pollen from the anther
to the stigma of the same flower or another flower on
the same plant.

6. Agents of pollination
Insect pollination –
when pollen grains are
transferred by insects
such as, bees,
butterflies, ants and
other insects from the
anther of a flower to
stigma of the same or
another flower.

7. Agents of pollination cont’d
Wind pollination-
when pollen grains are
blown by the wind from
one flower to another or
to the same flower.

8. Characteristics of insect and wind
pollinated flower
Insect pollinated Wind pollinated
Large brightly coloured petals Small dull coloured petals
Flowers have scent Flowers doesn’t have any scent
Filament is strong and is inside the
flower
Filament is thin and hang outside the
flower
Pollen grains are sticky or hairy and are
few in amount
Pollen grains are light and numerous
Stigma also hairy and sticky and is in
the flower.
Stigma feathery to catch pollen and
hang outside the flower.
