2. Place the carefully prepared microscope slide in position and keep in place firmly gripped with the clips. 3. Look through the microscope’s eyepiece and then move the focus knob carefully for the image to come into clear focus. 4. Slightly adjust the microscope’s condenser and amount of illumination for optimum light intensity.Onion Root Mitosis. It is common to see photomicrographs of onion root cells when demonstrating how cell division takes place in plants. Onions have larger chromosomes than most plants and stain dark. The chromosomes are easily observed through a compound light microscope. The cells pictured below are located in the apical meristem of the onion ... Onion bulb Figure 12.

View the slide under high power. Observe each cell and determine what phase of mitosis it is undergoing. Do not worry about distinguishing prophase from prometaphase. Count a minimum of 200 cells, changing your field of view as many times as ... The best light microscope can show details that are 0.2µm apart and need a magnification of roughly x1500 so that our eyes can see it - this allows us to see larger cell structures.

Blood cells are cellular structures found suspended in the plasma of the blood. Human blood contains a number of blood cells on the basis of their purpose and structure. The red blood cells occupy most of the blood cells in the blood, followed by white blood cells and then the platelets.

At 40X magnification, the microscope enlarges a 2 mm part of the onion and at 100X the microscope enlarges 0.8 mm of the cell. At both 40X and 100X you can online see a zoomed out image of the cells.Observations of onion root tip squash. Scan the microscope under the 10x objective.
