Understanding Mitosis: The Process of Cell Division and Chromosome Distribution

Mitosis is a fundamental process in cell biology that involves the organization and distribution of chromosomes to daughter cells. This intricate cycle includes distinct phases: Interphase (where the nuclear envelope and chromatin are visible), Prophase (nuclear envelope disappears and chromosomes condense), Metaphase (chromatids align at the cell's equator), Anaphase (chromatids pull apart to poles), and Telophase (chromosomes dissolve and new nuclear membranes form). Explore the phases of mitosis and their importance in growth and reproduction, illustrated with various cell types like Allium and Coregonus.

  3. Interphase

  4. nucleolus (if any) still visible INTERPHASE: nuclear envelope clearly visible chromatin, NO chromosomes, yet http://www.fed.cuhk.edu.hk/~johnson/photomicrographs/mitosis/animal/animal_interphase.htm

  5. PROPHASE nuclear envelope disappears nucleolus disappears chromosomes become visible http://www.ac-dijon.fr/pedago/svt/documents/mitose/prophase.gif

  6. PROPHASE Allium root tip Coregonus blastula

  7. METAPHASE chromatids spindle centriole http://www.chembio.uoguelph.ca/educmat/chm736/cycletx.htm chromatids line up on the equator.

  8. METAPHASE Allium root tip Coregonus blastula

  9. ANAPHASE chromatids migrate to each pole. http://www.blc.arizona.edu/courses/181gh/Lectures_WJG.01/mitosis_F.01/mitosis.html

  10. ANAPHASE Allium root tip Coregonus blastula

  11. TELOPHASE http://www.bmb.psu.edu/courses/bisci2/mitosis/mitosis.htm Chromosomes dissolve. Mitotic spindle dissolves. Nuclear membrane forms. New nucleoli form.
