The cell cycle of an onion root-tip cell is approximately 24 hours. This means an onion cell divides about once every 24 hours.
Details of the Onion Cell Cycle
The provided reference highlights a specific characteristic of onion cell division:
- Onion root-tip cells have a cell cycle of approximately 24 hours.
- Cell division in onion root-tip cells usually takes place about two hours after sunrise. This is important for studies examining dividing cells. To maximize the number of dividing cells to score, roots grown on water should be cut about two hours after sunrise.
