four haploid cells.
Mitosis
During Mitosis what are the daughter cells like compared to the parent cell
Identical
Meiosis
What are the daughter cells produced compared to the parent cell.
Half number of chromosones
What type of cell goes through mitosis to duplicate?
Somatic cells
What type of cell does meiosis produce
Gamete/ Germline
A germline cells divides meiosis it undegoes two divisions name them.
- Seperating homologous chromosones
- Separating chromatids
What is cellular differentation
Certain genes are switched off and certain genes are left switched on.
What does cellular differentation allow you to carry out?
allows a cell to carry out Specialised functions.
What is the function of a sperm cell
Swims to fuse with egg to produce a zygote
