The different types of microscopes include compound, dissection, confocal, Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM). These microscopes vary widely in complexity and design. Many operate using light and illumination, while others use electron scattering and produce images in a two-dimensional or three-dimensional design.Know More
For viewing glass slides, compound and confocal microscopes make good choices. Compound microscopes use visible light for producing two-dimensional images. These microscopes rank among the most expensive microscopes and the most frequently used. Compound microscopes produce high levels of magnification and emit low resolution. They feature mechanical focusing mechanisms and use air as an operational medium. They produce images using light absorption and let users adjust settings using magnification adjustments.
Confocal microscopes also let scientists view specimens on glass slides. They use laser light rather than visible light, which uses longer wavelengths. Images placed on the slides of confocal microscopes undergo viewing with a complex scan. This scan then transmits images to scientists in a digital format. Confocal microscopes also use air as a medium and have a digitally controlled computer focusing mechanism. These microscopes also produce two-dimensional images. SEM microscopes, however, produce three-dimensional pictures using electron illumination. They produce black and white images, and feature high magnification and high resolution for clear and accurate visual production.Learn more about Biology
Microscopes help scientists see tiny organisms and understand the fine details of cells, fibers, nuclei and other structures invisible to the naked eye, which in turn influences education and research, helping scientists disseminate critical information to others. Microscopes facilitate the study of many scientific branches, including biology and immunology. Scientists use specific types of microscopes, such as electron microscopes, for facilitating microscopic studies within their own disciplines.Full Answer >
Microscopes are currently used in a variety of disciplines, fields and contexts. For example, biologists use microscopes to study tiny organisms, such as bacteria and algae. Doctors and lab workers often use microscopes to investigate biological samples for parasites.Full Answer >
Ecosystems, or communities in which living organisms and nonliving elements interact, fall into two categories: aquatic and terrestrial. Aquatic ecosystems are found in bodies of water, either marine or freshwater. Terrestrial ecosystems are found on land, either forest, desert, grassland or mountain.Full Answer >
The types of protists, which are eukaryotes, that aren't animals, fungi or plants include euglenoza, alevolates, stramenopiles, red algae, slime molds and choanoflagellates. The alevolate group includes ciliates, sporozoans and dinoflagellates. The stramenopile group includes diatoms, golden algae, green algae and water molds.Full Answer >
