Fertilisation

1. Fertilisation occurs in the _ _ _ _ _ _ _ when the _ _ _ _ _ and the _ _ _ _ meet.

2. The fertilised ovum is called a _ _ _ _ _ _.

3. As it travels to the uterus, it continues to divide until it’s a _ _ _ _ of _ _ _ _ _ called an _ _ _ _ _ _.

Pollination1. There are two types of pollination:

_ _ _ _ and _ _ _ _ _ _.2. Insect pollinated plants have

_ _ _ _ _ _ _ _ coloured petals and a sweet smell. Their stigma is _ _ _ _ _ and the anthers are _ _ _ _ _ _ the flower.

3. Wind pollinated plants have small, _ _ _ _ petals and _ _ _ _ _ _ _ _ stigmas. They have no scent and the anthers hang _ _ _ _ _ _ _ the flower.

Fertilisation

1. The male sex cell in plants is the _ _ _ _ _ _ and the female sex cell is the _ _ _ _ _.

2. When the pollen lands on the stigma it forms a _ _ _ _ _ _ _ _ _ _ to take the pollen to the ovary.

3. The fertilised ovule or _ _ _ _ _ _ becomes the _ _ _ _. The ovary becomes a _ _ _ _ _.
