- Cell Cycle
- Interphase
- Cell VOLUME increases
- Sub-cellular structures/organelles replicate
- DNA REPLICATES
- Chromosomes not visible
- Longest stage in the cell cycle
- Processes occur (respiration and protein synthesis)
- Stage of cell activity before cell division
- Mitosis
- Metaphase
- Spindle fibres attach to centromeres
- spindle fibres pull the chromatids to line them up at the EQUATOR
- Spindle fibres attach to centromeres
- Prophase
- Chromosome coil and CONDENSE (shorten and thicken)
- Chromosome are visible
- SISTER CHROMATID are joined together by CENTROMERE
- Spindle fibres develop from the CENTRIOLE at OPPOSITE POLES of the cell
- Chromosome coil and CONDENSE (shorten and thicken)
- Anaphase
- Spindle fibres CONTRACT, dividing the centromeres into 2
- Spindle fibres pull chromatids APART to OPPOSITE POLES of the cell
- Energy for this is required which comes from respiration rom mitochondria
- Telophase
- Nuclear envelope and nucleolus develops
- Chromosome reach the poles
- Chromosomes de-coil and DE-CONDENSE into chromatin (elongate)
- No longer visible under a light microscope
- Cell division (mitosis) - a diploid cell dividing into 2 GENTICALLY IDENTICAL DIPLOID DAUGHTER cells
- Metaphase
- Cytokenesis
- 2 GENTICALLY IDENTICAL DIPLOID DAUGHTER cells are produced from the mother cell
- Cytoplasm and cell membrane divides
- Cell division (mitosis) - a diploid cell dividing into 2 GENTICALLY IDENTICAL DIPLOID DAUGHTER cells
- Interphase
- Spindle fibres pull chromatids APART to OPPOSITE POLES of the cell
- Energy for this is required which comes from respiration rom mitochondria
