13. Pollination: Wind Pollination
Pollination happens when pollen reaches the carpel.
Wind Pollination

14. Fertilisation

15. Fertilisation:
Fertilisation happens when the male gamete (pollen) and the female gamete (ovule) fuse to form a zygote.

16. When the pollen grain lands on the carpel it develops a pollen tube which grows down from the stigma, through the style and into the ovary where fertilisation takes place

17. Seed & Fruit Formation

18. The zygote grows to become seed and fruit.

19. The seed of a broad bean is surrounded by a tough outer covering called the testa. Inside this the seed consists of stores of food. The part of the seed growing up from this is called the plumule. This grows during germination to form the future shoot. The part growing down from the seed is called the radicle. This grows to form the future root

39. To investigate the conditions necessary for germination
Procedure:
Place cress seeds in cotton wool in each test-tube.
Add moist cotton wool to one
Add water which has cooled after boiling to another and cover it with oil (this means there will be no oxygen).
Add dry cotton one to another (no water).
Keep another in the fridge (no heat).
