Interactive Practice Activities:
Virtual Lab Investigation: Comparing Mitosis in Plant and Animal Cells
Overview
In this virtual lab investigation, you will study the process of mitosis using the images of prepared slides of onion
root tip and early whitefish embryo. These images show dividing cells in various stages of mitosis

Turn on the lamp of the microscope by clicking on it.
Drag an onion root tip slide on to the microscope stage.
Click on the eyepiece to view the slide.
Click on the coarse and fine focus knobs to focus the image.
Click on the microscope objectives on the lower left corner to change magnification. Focus again
if necessary.
Click and drag the slide around the field of view to examine it.
Locate cells in various phases of mitosis. Draw and label a cell undergoing each phase of mitosis in a
data table.
Repeat steps 2-7 to examine additional slides of onion root tip until you have identified cells in each
mitotic phase.
Repeat procedure to examine and compare whitefish embryo cells undergoing mitosis to the onion root
tip cells.

If it takes 3 hours for a cell to complete its cell cycle and divide into 2 cells, then how many cells will be produced
from this single cell in 18 hours?
