- Interphase:: longest stage, cells synthesise new organelles, proteins and DNA
- Mitosis:: cell division, produces two genetically identical daughter cells
- Importance of mitosis:: growth and repair
- Stages of mitosis: interphase, prophase, metaphase, anaphase, telophase, cytokinesis
- Prophase:: DNA condenses into chromosomes, nuclear enveloped break down, centrioles move to opposite poles
- Metaphase:: spindle fibres attach to centromeres and line sister chromosomes up at the metaphasic plate
- Anaphase:: spindle fibres pull sister chromatids apart to opposite poles
- Telophase:: chromosomes uncoil, nuclear envelope reforms, spindle fibres break down
- Cytokineses:: division of the cell at the end of mitosis to from two new daughter cells
- Sister chromatids:: identical chromatids formed by DNA replication joined by a centromere
- Mitosis in animal cells:: occurs in all cells, cells become rounded, involves centrioles and micro filaments, spindle fibres break down before cytokinesis
- Mitosis in plant cells:: only meristematic cells, cells don’t change shape, no centrioles of microfilaments, spindle fibres remain during cytokinesis
- Consequence of uncontrolled mitosis:: cancerous growths
