Using the information from your practical work and referenced supplementary material from secondary sources, discuss the behaviour of the chromosomes during mitosis and meiosis in each stage of cell division, including the similarities and differences between plant and animal cells. Ensure you cover: 

• Mitosis - interphase, prophase, metaphase, anaphase, telophase

• Meiosis - interphase, prophase I, metaphase I, anaphase I, telophase I, cytokinesis, interkinesis, prophase II, metaphase II, anaphase II, telophase II, cytokinesis
