Pollination w i n d i n s e c t b r i g h t l y s m a l l i n s i d e There are two types of pollination: _ _ _ _ and _ _ _ _ _ _. Insect pollinated plants have _ _ _ _ _ _ _ _ coloured petals and a sweet smell. Their stigma is _ _ _ _ _ and the anthers are _ _ _ _ _ _ the flower.

Fertilisation p o l l e n o v u l e p o l l e n t u b e z y g o t e The male sex cell in plants is the _ _ _ _ _ _ and the female sex cell is the _ _ _ _ _. When the pollen lands on the stigma it forms a _ _ _ _ _ _ _ _ _ _ to take the pollen to the ovary. The fertilised ovule or _ _ _ _ _ _ becomes the _ _ _ _.
