Fertilisation

Pollination

Insect Polination: The insects and bees are attracted towards the nectary where sugar is made, and the petals give out scent, and are coloured to attract the insects.The insect has to reach the nectar, which is at the bottom of the flower. While it reaches it, some of the ovules made by the ovaries rub off onto the insect. The nexttime the same insect goes to another plant to collect nectar, the ovaries which were stuck to the insect rub off against the stigma, which will allow fertilisation to occur.
