- Mitosis
- makes new cells for growth and Repair
- Mitosis is when a cell reproduces itself by splitting to form identical offspring
- When a body cel divides to make identical cells- same number of chromosomes
- 1.When a cells not dividing the DNA is in long strings
- 2.When it gets a signal- the Dna duplicates. Form X-shaped chromosomes. Each arm is an exact duplicate of the other
- 3.The chromosomes line up at the center and fibre paticles pull the apart. Each arm goes to the opposite end
- 4.Membranes form around each set and become the nuclei of the two cells
- 5.The cytoplasm divides
- Asexual reproduction uses mitosis-e.g strawberry plants form runners in this way to become new plants
