Mitosis in Real Cells

To study mitosis, biologists often look at particular cells. Remember, that mitosis occurs only in areas of growth, so finding a good spot to study it can be challenging. Two specimens are commonly used by biologists to study mitosis: the blastula of a whitefish (early embryo) and the root tip of an onion (an area of rapid growth).

Mitosis can take several hours to complete. Scientists will make slides of cells that should be undergoing mitosis in order to find a particular cell in any of the stages - prophase, metaphase, anaphase, telophase. Your task is to look at photographs of actual slides and identify the stages of mitosis.

Click on the whitefish or the onion to get started.
