This topic compares mitosis and meiosis. Root tip squash is the linked practical.
What you need to know
- Cell cycle Interphase (G1, S, G2), mitosis and cytokinesis.
- Mitosis Prophase, metaphase, anaphase and telophase produce two genetically identical diploid cells for growth and repair.
- Meiosis Two divisions produce four haploid cells, with crossing over and independent assortment creating variation.
- Cancer Uncontrolled cell division when the cell cycle is not regulated.
Common mistakes in 1.6 Cell Division
- Saying DNA replicates during prophase.
- Mixing up mitosis and meiosis outcomes.
- Confusing chromatids and chromosomes.
