Adolescence – children become teenagers
Adulthood – your body is fully developed
•Old age / elderly – the last stage in the life cycle of a human

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
