Onion root tip mitosis lab report pdf answer key.

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.View Lab Report - Onion Root Tip Lab.pdf from ENG 111 at Rancho Dominguez Preparatory School.

Unlike meiosis, which is also a type of cell division, mitosis results in the production of two diploid daughter cells.The root tip has been stained with dyes that concentrate in the chromosomes, so you should be able to see them clearly and be able to distinguish cells in interphase, the different stages of mitosis, and cells undergoing cytokinesis.This lab was an experiment designed to analyze how many cells could be observed in each part of mitosis for different areas of an onion root. First, with a prepared slide, area X and Y were located and each counted and recorded of what stages were observed. Then, another onion root tip was prepared and area Z was located.
