Examining Paramecium Using Darkfield Microscopess
First and foremost, before conducting any form of experiment and observation, the microscope enthusiast must know the basic parts of the darkfield microscope. In doing so, he will know how to use this better.
Parts of a Darkfield Microscope:
A darkfield microscope has ocular and objective lenses. These are used to make the specimen and sample larger for observation. The condenser and focusing knobs are used to adjust the sizes of the specimen and the sample while it is being observed. The stage is the platform where the specimen and the sample are placed.

It also helps to know how to calculate for the magnification needed in the experiment. The microscope enthusiast must also know which lens can give him the most depth when the sample or specimen is focused. He should also know which lens gives him the widest view? There is also an objective lens that should be use at the beginning of the experiment.
A microscope enthusiast must also be able to estimate the sizes of the things that are placed under the microscope. This can be done by comparing the objects with one another and by estimating the preferred size of the field. Eventually, the dark field microscope is calibrated in such a way that the ocular micrometer is achieved.
Biological Molecules and Microscopes
Thanks to microscopes and modern-day technology, we can understand the scientific world better. We can also have a better perception of the specimen – right in front of us. Picture this: we can actually see a biological molecule!
But before conducting any study involving biological molecules – such as paramecium, one must know how the specimen reacts with other elements. Some experiments involve dropping starch, iodine and other solutions to the sample to see how the paramecium reacts to this.
There are also some experiments that observe whether the paramecium is attracted to glucose, sucrose and starch. By understanding all these, the microscope enthusiast will be able to understand and know the purpose of paramecium in the first place. Judging from the reactions of the specimen and the sample, one can make a reasonable guess and even a hypothesis over the changes that were seen during the whole experiment.
Chromatography and Spectroscopy
When observing paramecium by using darkfield microscopes, a chromatography and spectroscopy test is also conducted. This paper chromatography will not work properly if there are problems in spraying the element.
Therefore the observer must first know the name of the spray reagent for the amino acids. He must also know the Rf value. If he has no idea how to determine it, the process can be learned.
For easy access, the enthusiast can plot the data of the absorption spectrum as well as the standard curve of how the paramecium reacts to the elements. Supposing that the development of the spectroscopic experiment results to a method that is measured by the amount of the chemical in the solution, the observer can see what exactly is the purpose of the paramecium as it absorbs the element.
Paramecium Cells
The observer must also identify the large organelles of the paramecium when observing it through the darkfield microscope. The basic parts are the nucleus, nucleolus, chloroplasts, central vacuole and the large mitochondria. It is also important to know what these parts do. They reflect why the paramecium acts the way it acts.
The important point to remember when handling paramecium is that this can be readily obtained for darkfield microscope examination. Fixing it with formalin and a sonic dissection is the first step when conducting the experiment. The structures of the paramecium includes mitochondira, trichocysts and macronuclei are reflected in the various stages of the fragmentation and the explosion of the paramecium’s pellicle.
The darkfield microscope also reveals the fiber systems that are connected to the paramecium. It is intimately associated to the paramecium’s pellicular membrane and this helps in corresponding the fibrillar lattice system.
The pellicle consists of thin membrane that is not structured. The outer system has a continuous network which corresponds to the positioning of the system and the pellicles. Whenever the cross bars of the lattice are thick, then this means that the paramecium are attached to both points.
The kinetics of the paramecium have discrete units. Every unit consists of the ciulim, the ciliary basal body and the tapering fibril. These parts are responsible for the paramecium to pass through the cilliary ring of its pellicle. It also terminates the internal basal body or the kinetosome.
