What is a gamete
A gamete is a sex cell and is involved in reproduction.
Gametes genetic information
Gametes are HAPLOID, meaning they contain only half of the genetic information of diploid cells.
Chromosomes sets
In humans - an egg and sperm cell contain 23 chromosomes (1 set).
Where are the female gamete’s produced
The female gametes are eggs and are produced in the ovaries
Where are the male gametes produced
The male gamete is sperm and is produced in the testes.
Features of a sperms cell
The tail enables the sperm to swim to the egg
Small
They have little cytoplasm so no real food store
What is a female gamete’s called in plants
The female gametes are ovules
Where is the male gamete called in plants
The male gamete is pollen and is produced in the anther.
Features of egg cell
They are large (in comparison to sperm)
They have lots of cytoplasm so have a large food store
Cannot move by itself
Fertilisation
Fertilisation is the fusion of the nuclei of the two haploid gametes to produce a diploid zygote, which divides to form an embryo
