Pollination• Pollen is transferred from anther to stigma
Self-pollination
Cross-pollination
•Nature pollination happens in two ways:-By birds and insects
-By wind
FertilisationThe pollen join with the egg/ovule to form a seed
Seed production
Seed dispersalSeeds are dispersed (spread) by many ways, such as:
Wind dispersal
Maple Dandelion
Water dispersal
Coconut Cattail
Lotus
-Animal dispersal
Blackberries
Acorn
Explosive action
HazelBeans
Germination
