The onion root tips can be prepared and squashed in a way that allows them to be flattened on a microscopic slide, so that the chromosomes of individual cells can be observed easily.

What are onion root tip cells doing when they are not undergoing mitosis?

5. What are the plant & animal cells doing when they are not actively undergoing mitosis? They are undergoing Interphase where the chromosomes copies itself in the nucleus.

Why would onion root tips be a good choice for cells to be observe mitosis in lab?

Why are there more cells in mitosis in the root tip than in the woody stem?

The apical meristem, just beneath the root cap, contains most of the root’s dividing cells. Therefore, cells in this area must complete the cell cycle often. … In the absence of these signals, cells begin dividing to produce secondary roots, leading to a greater number of cells in mitosis.

Why does a cell undergo mitosis?

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). … The major purpose of mitosis is for growth and to replace worn out cells.

Why are onion root tips suitable for genetic analysis?

The size of chromosomes makes Allium cepa tips as favourable material for the study of the effects of chemicals on frequency of CAs which are biomarkers of damage of genetic material. The root tip cells have a very low spontaneous aberration frequency and a stable chromosome number.
