Onion root tip

You: I think that the best option is the onion root tip cells. 

Prof. Collins: I agree! Onion root tips are ideal for observing mitosis due to their high concentration of actively dividing cells in the root meristem. The root meristem contains a region called the apical meristem, where rapid cell division occurs to facilitate root growth. This region is rich in cells undergoing mitosis and provides a consistent and easily accessible source for observing the various stages of mitosis.

You: Plus, they are cheap and so easy to get a hold of!

Prof. Collins: Yes, that actually makes them a practical choice for laboratory experiments.

In preparation for slide observation identify the stages of mitosis and the order in which they occur.
