What is
pollination?
Just as with humans, the formation of a new plant begins
with fertilisation.
The pollen must fertilise the ovule.
For this to happen the pollen grain must get from the
anther to the stigma.
How could it do this?
Share new information
There are two main methods of pollination:
Insect
Wind
What do you think the
advantages and
disadvantages are of
these two types of
pollination?
ACTIVITY………………..
Q1. State the difference between self-pollination
and cross-pollination.
Q2. Describe how wind and insect pollination work.
Q3. Explain in detail the difference in structure
between an insect-pollinated and a wind-pollinated
plant.
Challenge: Below are pictures of pollen grains. Decide
what type of pollination they represent based on their
adaptations. Explain your reasoning.
