Insect pollination
- Pollen grains are spiky to stick onto pollinators
- pollination is the transfer of pollen from the anther to the stigma
- Insect pollinated flowers are colourful, scented and have very sticky Stigmas within the flower
Wind pollination
- Wind pollinated flowers are neither colourful or scented as they dont need to attract any insects
- They have feather stigmas that hang out of the flower
- Pollen grains are light and streamline to blow in the wind
Fertlisation
- The zygote develops into an embryo
- In plant the zygote develops into seeds
-
- The ovary wall becomes the fruit
Process
- From the stigma the pollen grains grows a pollen tube
- which grows towards the ovary
- on reaching the ovary the tube bursts
- releases the male gamete
- once inside the gamete nuclei fuse together
- This is Fertlisation
