Onion Root Tip Cell Mitosis

Prophase

Nuclear membrane breaks down, chromatin condenses, mitotic spindle forms and attaches to kinetochores.

Metaphase

Microtubules align chromosomes along metaphase plate.

Anaphase

Kinetochore microtubules shorten, pulling sister chromatids to opposite poles, polar microtubules elongate, lengthening dividing cell.

Telophase

Nuclear membrane reforms, chromatin decondenses, and cell plate begins to form.
