25pk Onion Mitosis - Prepared Microscope Slide - 75x25mm

This classroom pack contains 25 prepared microscope slides showing onion root tip mitosis, supplied in a polystyrene storage box. Each slide measures 75mm by 25mm. The slides are sectioned from allium root tips. Root tips contain a meristem where cells divide continuously, so a single thin section captures cells at every phase of mitosis at once, with prophase, metaphase, anaphase, and telophase all present in the same field. That is why onion root tip is the standard preparation for cell division work, since a live culture would require timing while a prepared section delivers the full sequence on demand. The slides are professionally prepared and labeled for identification, and the storage box keeps the set together and protects the edges between sessions.
