Observing Mitosis Lab nclark.net. Jan 14, 2015 · Introduction and Objective In Mr. Wong’s 7th period bio-honors class, we did a lab experiment on the processes of mitosis and the different phases as seen under a microscope. The objective of this experiment was to calculate the percentage of cells in each of the phases of mitosis.There were two different slides, one of onion root…, treatment for onion root tip tissue to be alive, and the lowest concentration for the treatment to be effective over the selected time period. From this experiment, we can select the optimum colchicine concentration treatment that produces cells only at prophase and metaphase. 2..

Does this make sense? The most onion root tip cells are interphase so yes this does make sense. 2.As a cell grows, what happens to its surface area-to-volume ratio (hint: think of a balloon being blown up)? How does this ratio change with respect to cell division? Abstract In this lab, onion root tip slides were observed within their zone of division to classify which of the five phases of mitosis each cell was in. The purpose was to calculate the percentage of cells in each phase and to calculate the length of time the cells spend in each phase. The majority of cells, 76.9%, were in interphase and the fewest number of cells, 3.5%, were in anaphase.

Onion Root Tip Mitosis Lab Protocol Onion root tips are used because the root of a plant is constantly growing and looking for water. This growth is mitosis over and over again. Mitosis is how a root/plant grows. The cells that you will be looking have will be treated with a fixative. This fixative freezes the cells in the exact place there were Mitosis in Onion Root Tip. The meristamatic cells located in the root tips provide the most suitable material for the study of mitosis. The chromosome of monocotyledonous plants is large and more visible, therefore, onion root tips are used to study mitosis. Based on the kind of cells and species of organism, the time taken for mitosis may vary.
