Here is an article about the: Machining a Dark field Microscope, that is it possible for a better condenser design that will reduce the time and effort switching between bright field and dark field.
The experiment uses a modified LOMO Biolam (Multiscope) with more potential in transmitted light than my modified Monolux microscope. The capability […]
There is nothing that more conspicuously displays the perfection of the works of Mother Nature than a comparison of them with the finest works of art. The contrast between the one and the other is exceedingly striking, and humbling to the pride of man. His best performances, when examined by the microscope, appear coarse and […]
About the year 1826, Dr. Goring discovered that the structure of certain bodies could be readily seen by some microscopes, but not by others. He called these bodies as test objects. In the course of his experiments, he was led to the conclusion that there were two distinct powers in a microscope, namely, defining and […]
There is a tendency to overlook the fungi when thinking about plants. Unlike plants, fungi are not green in color, and they grow without real stems, roots or leaves. Many lead to a parasitic existence for they lack chlorophyll and they are unable to manufacture their own food. Fungi include the yeasts, molds, mildews, and […]
The cell is the fundamental building blocks of all living things. It is the structural and functional unit of all living organisms. To obtain a detailed image of cells, microscope is necessary. The cell theory was first developed by Matthias Jakob Schleiden and Theodor Schwann in 1839. Important functions of an organism occur within the […]
Fixation Process
1. Remove the vitelline membrane from the blastoderm and discard it using the forceps and the camels hair brush. Then with a pipette, remove any excess saline solution from the watch glass. Gently position the blastoderm with a camels hair brush to keep its tissues flat and unwrinkled.
2. Fill the pipette with a fixative […]
Accurate observation of the development of a chick embryo and analyzing the details of its formation necessarily needs a microscope. Microscope is very essential and significant in this kind of study and observation. The suitable specimen for embryonic study is the chick embryo. Several procedures are being observed while preparing chick embryos. These are the […]
Much of the discovery of medicine happened in bacteriologists laboratory over the microscope glass slide. A few examples of microscopic experiments are those interminable rows of flasks, broths, and cultures of Pasteur, the fleck of greenish mold that awakened the curiosity of Fleming and the study of Behring on effects of deadly bacillus of diphtheria […]
Birds are the only animals with feathers and scales. Their scales in their feet indicate their ancestral link to reptiles. Feathers are modified scales, being non living outgrowth of certain skin cells. Examples of these non living outgrowths are the human hair and fingernails.
There are two kinds of feathers foe birds. The contour feathers that […]
Developmental biology is partly concerned on the study of the formation of life which is known as embryology. Developmental biology focuses on how all forms of life begin and how they have developed fully into functioning organisms while the focus of embryology is much narrower. Embryology deals with the study of formation of life and […]
