Materials and Methods: Biology 1108 Lab Practical 1
To successfully conduct this practical, you will require a range of materials. Firstly, you will need a microscope and slides. Additionally, you will need prepared slides of plant and animal cells, as well as a variety of staining reagents. Furthermore, you will need a cover slip and immersion oil.
Finally, you will need a notebook and pen for recording your observations.
The experimental procedures for this practical involve several steps. Firstly, you will need to prepare a wet mount of a plant or animal cell. To do this, place a drop of water on a slide and gently place the specimen in the center of the drop.
Next, carefully lower a cover slip over the specimen, avoiding the formation of air bubbles. Once the wet mount is prepared, you can observe the specimen under the microscope.
To enhance the visibility of certain cell structures, you may need to stain the specimen. To do this, add a drop of staining reagent to the edge of the cover slip and allow it to diffuse under the cover slip.
After a few minutes, observe the specimen under the microscope to see the stained structures.
When using the microscope, it is important to follow certain safety precautions. Firstly, always carry the microscope with both hands, one hand supporting the base and the other hand supporting the arm. Secondly, never look directly into the light source of the microscope.
Finally, always clean the microscope and its components after use.
