What can be seen by observing the meristem of the onion root?

Observing the meristem of an onion root reveals regions of active cell division, characterized by densely packed cells that are small and undifferentiated. This area, known as the root tip or apical meristem, is crucial for root growth and development. One can also see the organization of cells into distinct zones, including the zone of cell division and the zone of elongation. Additionally, the presence of root cap cells protecting the meristem can be noted.
