mitosis

• Mitosis creates two identical diploid cells used for growth, tissue repair and asexual reproduction in plants and animals
• what are diploid cells?

  cells that contain 2 copies of each type of chromosome
• Mitosis has four key stages prophase metaphase anaphase and telophase
• Prophase is the first stage of mitosis where chromosomes condense and become visible, sister chromatids join at the centromere and the nuclear envelope breaks down and spindle fibres form.
• Metaphase is the second stage of mitosis where spindle fibres attach to the centromere and chromosomes lineup along equator cell
• Anaphase is the third stage of mitosis where spindle fibres shorten causing sister chromatids to be pulled to opposite ends to cell requires ATP
• telophase is the fourth stage of mitosis we're chromatids reach cell pole and the condense back into chromatin and nuclear envelope reforms and spindle fibres Break down
• Cytokinesis is when the cytoplasm divides into two equal parts producing two genetically identical daughter cells.
