Answer to Question #61736 in Biology for Sanjukta Ghosh

Question

Why don't onion root tips show mitotic stages?

It was back in the winter that we did the Onion root tip experiment in college. We were able to see wonderful stages but now in this monsoon-autumn transition the root tips hardly show any mitotic stage. Why is it so?
P.S I live in India in the plateau region of West Bengal.

Answer 1

Mitosis is less evident in the monsoon-autumn period because the plant follows its natural biological cycle. Intensive growth is not typical for the plant in this period. Therefore, onion root tips mitiosis is less evident.
