What are sex cells known as?
Gametes

By what process are gametes produced?
Meiosis (MAKING EGGS)

What is the difference between mitosis and meiosis?
Mitosis - parent cell has 46 chromosomes, divides into two daughter cells, which are identical to parent cell. Meiosis = Parent cell has 46 chromosomes, divides into two daughter cells that have 23 chromosomes. Meiosis is for sexual reproduction.

How do cells divide in the testes and ovaries?
By meiosis.
4 of 10
What type of cells are produced by meiosis?
Sex cells or gametes, eggs and sperm.
5 of 10
Explain how four gametes are formed from one cell?
There are two sets of cell division. A body cell divides into two and each divides again.
6 of 10
What is a way to remember meiosis
M (Making) E (Eggs) iosis.
7 of 10
What happens at fertilisation?
Gametes from each sex join, and a new single body cell is created with new pairs of chromosomes.

What are gametes in humans?
The sperm and the ova.

What happens after meiosis?
A new individual develops by the cells repeatedly dividing by mitosis.
