Receives sperm from the penis during sexual intercourse. |
| 26 |
What happens if a sperm meets an egg? |

| 27 |

| 31 |
What happens on day 5 of menstrual cycle? |
Bleeding stops-uterus lining begins to regrow. |
| 32 |

It can then implant into the uterus lining and form an embryo (ball of cells) |
| 33 |

| 41 |

It is moved along the oviduct towards the uterus by the cilia. |
| 42 |
When can pollination occur? |
Due to insect or wind. |
| 43 |
When does fertilisation of the ovule occur? |
When pollen transferred from the anther to the stigma. |
| 44 |
Where does the pollen nucleus move down? |
The tube. |
| 45 |
