Cell Division

• All cells develop from pre-existing cells
• Cells divide and survive from one generation to the next
• This gives rise to the continuity of life

• Coiled thread like structure of DNA and protein that becomes visible in the nucleus during cell division

• 46

• Short section of DNA which codes to make a protein

1. For Mitosis, 2 daughter nuclei are formed

1. For Meiosis, 4 daughter nuclei are formed

2. For Mitosis, the daughter nuclei are identical to parent cell

2. For Meiosis, the daughter nuclei have variation compared to parent cell

3. For Mitosis, the daughter nuclei have the same number of chromosomes as parent cell

3. For Meiosis, the daughter nuclei have half the number of chromosomes as parent cell
