Pollination• Pollen is transferred from anther to stigma

Self-pollination

Cross-pollination

•Nature pollination happens in two ways:-By birds and insects

-By wind

Page 17: Life cycle

FertilisationThe pollen join with the egg/ovule to form a seed

Seed dispersalSeeds are dispersed (spread) by many ways, such as:

Wind dispersal
