Onion Root Mitosis
- 1) Interphase is considered the first and last stage of plant cell division. ...
- 2) Prophase. ...
- 3) Metaphase is the middle stage at which point all the chromosome pairs line up in the center of the cell along spindle fibers that pull to either side of the cell.
- 4) Anaphase. ...
- 5) Telophase.
What stage are most onion root tip cells in?
Although the cells of an onion root tip are actively growing, the longest and most common phase for this tissue is still Interphase. Cells spend the longest amount of time in interphase to ensure that cell size has increased properly and DNA has been replicated accurately prior to mitosis and cytokinesis.
What happens in the 5 stages of mitosis?
Prophase – The chromosomes shorten and thicken. Metaphase – Chromosomes line up in the middle of the cell. Anaphase – Chromatids break apart at the centromere and move to opposite poles. Telophase – Two nuclei formed after nuclear envelopes reform around each group of chromosomes.
