  • Mitosis
    • When a cell reproduces itself by splitting to form two identical offspring
    • Makes new cells for growth and repair
    • 1. In a cell that's not dividing, the DNA is spread out in long strands
    • 2. DNA copies itself and forms X-shaped chromosomes that are exact duplicates
    • 3. The chromosomes line up at the centre of the cell and cell fibres pull them apart, to opposite ends
    • 4. Membranes form around each set of chromosomes, to become the nuclei of the 2 new cells
    • 5. The cytoplasm divides to make 2 new identical cells
    • Asexual Reproduction
      • Can happen in plants as well
