Human fertilisation

• Fertilisation = the union of a human egg and sperm cell
• The result of fertilisation is a fertilised egg cell, which contains the hereditary information from the male (via the sperm cell) and the female (via the egg cell)
• When one sperm cell succesfully entered the egg cell, than the membrane of the egg call undergoes changes so no other sperm cell is able to enter the egg cell anymore

Fertilisation = bevruchting

Fertilised egg

• A fertilised egg cell is called a zygote
  
• A zygote divides many times, creating a lot of cells containing the same hereditary (erfelijk) information
• The zygote (containing many cells) eventually implant in the uterus lining

What is fertilisation?

1. The release of the egg cell from the ovaries
2. The dividing of the zygote
3. Implantation of the zygote into the uterus wall
4. The union of an egg cell and sperm cell

The ovaries release a(n) ... egg

1. Fertilised
2. Unfertilised

The inner lining of the uterus is released when an egg is fertilised

1. True
2. False

A zygote contains the chromosomes (genetic information) of the male and the female

1. True
2. False
