Liver cell
Are somatic cells haploid or diploid?
They are diploid
Somatic cells are diploid, what does this mean?

What would happen if two haploid cells joined together?
The number of chromosomes in the resulting cell would be double the normal number
What happens to the number of chromosomes in a cell during meiosis?
The number of chromosomes is halved
Does mitosis or meiosis halve the amount of chromosomes in a cell?
Meiosis
After meiosis is the resulting cell haploid or diploid?
Meiosis results in a haploid cell
What is a haploid cell formed from meiosis called if it is capable of fusing with another haploid cell?
It is called a gamete
What is a gamete?
Gametes are haploid cells that are capable of fusion
What is another name for gametes?
Sex cells
How do gametes transmit genes from one generation to another?
Through sexual reproduction
What do gametes pass from generation to generation through sexual reproduction?
They pass genes
What are the gametes in humans?
Sperm and egg
What is fertilisation?
