Introduction: In this lab, you will examine the dividing root-tip cells of an onion. You will examine the. specimen to identify the various phases of the cell cycle, to see which phases cells spend. more time in, and you will answer related analysis questions to further your understanding of. the eukaryotic cell cycle. Pre-lab:During mitosis, the 23 pairs of human chromosomes condense and are visible with a light microscope. A karyotype analysis usually involves blocking cells in mitosis and staining the condensed chromosomes with Giemsa dye. The dye stains regions of chromosomes that are rich in the base pairs Adenine (A) and Thymine (T) producing a dark band.

In 1842, C. Nägeli first saw chromosomes and in 1888 W. Waldeyer named them. Walther Flemming studied and named the process of cell division as mitosis. Cell division occurs rapidly in growing root tips of sprouting seeds or bulbs. The most commonly used root tips in labs to study mitosis are onion, wheat, lentil, barley and alfalfa.Introduction: All cells come from preexisting cells and eukaryotic cells must undergo mitosis in order to form new cells.
