The photograph shows pea seeds with growing roots. (Source: © Sangita Pal / Alamy Stock Photo) Mitosis occurs in growing roots. A scientist allowed pea seeds to start growing in different concentrations of oxygen. Pea seeds were grown in oxygen concentrations of $$\(5 \%\)$$ and $$\(20 \%\)$$. After two days the root tips were removed. The tips were stained and observed under a microscope. The mitotic index for each root tip was determined.
