Mitosis Plants vs. Animals

While the main purpose of mitosis remains the same in plants and animals, the process contains similarities and differences between these two types of eukaryotic cells.
  • During Prophase, chromosomes condense
  • In Prometaphase, the nuclear envelope breaks down, the chromosomes move towards the metaphase plate, and the spindle grabs the chromosomes
  • In Metaphase, the chromosomes align at the equator
  • In Anaphase, they move towards opposite poles
  • In Telophase, the nuclear envelope appears again, chromosomes de-condense, and the spindle breaks down.
  • In Prophase, animal cells have centrioles that organize spindles while plant cells don't. Plants also have a pre-prophase band, which consists of actin and microtubules, that forms in the place where the cell wall will appear
  • During Prometaphase, the pre-prophase band of plant cells disappears.
  • During Telophase, animal cells have a contractile ring, which is made of actin and myosin, that forms halfway between the two nuclei in the dividing cell. In Plant cells, a phragmoplast, which is made of actin, myosin, and microtubules, forms in the center of the cell where the cell wall will appear
  • In Cytokinesis, the contractile ring in animal cells contracts and pinches the cell into 2 daughter cells. In plants, the phragmoplast extends and forms the cell wall.
  • In plants, mitosis occurs only in the meristem tissues. They are located at the tips of roots, shoots, and in the stem, between the xylem and phloem.
