Microscopes

Collectively they are known as microorganisms. They include bacteria, protozoans and other creatures.

The magnifying lenses in a light microscope are the objective lens and the eyepiece. The objective lens is located closest to the specimen and provides the initial magnification, while the eyepiece further magnifies the image for viewing by the observer. These two lenses work in combination to produce a magnified image of the specimen.

A scanning electron microscope (SEM) would be ideal for examining the shape and surface texture of small objects at very high magnifications. SEMs use a focused beam of electrons to create a detailed image of the specimen's surface, offering a 3D view with high resolution.

A thin and transparent specimen is placed on a microscope slide for observation under a microscope. Common samples include cells, tissues, bacteria, or small organisms. To keep the specimen in place and protect it, a coverslip is often placed on top before examination.

If you discovered an organism under a microscope, you would expect to see its cellular structure, such as cell walls, membranes, organelles like nucleus or mitochondria, and potentially any specialized features like cilia or flagella. Additionally, you may observe its size, shape, and possible movement or behavior.

Microscopic

The mirror in a microscope directs light from an external source, such as a lamp, onto the specimen being observed. It helps illuminate the specimen, making it easier to view. By adjusting the mirror, the amount and angle of light hitting the specimen can be controlled to optimize the image quality.

An electron microscope is typically used to view organelles, as it provides a higher resolution and can visualize smaller structures compared to a light microscope. Transmission electron microscopes (TEM) are often used to view organelles at high magnifications.

The stage manipulator knobs on a compound microscope are used to move the slide horizontally and vertically on the stage. This allows for precise positioning and focusing of the specimen being viewed under the objective lens.

There are many parts needed to make a microscope. Some of the parts of a microscope include the eyepiece lens, arm, base, tube, illuminator, objective lenses, diaphragm, and condenser lens.

Yes, a sperm sample can be examined under a microscope to assess its health. Parameters such as sperm count, motility, and morphology can be evaluated to determine if the sperm is healthy and capable of fertilizing an egg.

Microscope images can be found in scientific research papers, textbooks, online databases, and educational websites. Organizations like the National Institutes of Health (NIH) and universities often have digital libraries dedicated to sharing microscope images with the public. Additionally, you can find microscope images on platforms like Google Images and Flickr.

The draw tube of a microscope is the part that holds the eyepiece and allows the user to adjust the focus by moving it up or down. It also helps to optimize the distance between the eyepiece and the objective lenses for clear viewing.

The hole in the stage of a microscope allows light to pass through the specimen, making it possible to view the specimen under high magnification. The light source from below illuminates the specimen through this hole, improving visibility and image clarity. The hole also allows for the insertion of specialized accessories, such as condensers or filters, to enhance the quality of the image.

Light microscopes are used to view living organisms because they use light to illuminate the specimen, which is less likely to damage or kill the organism compared to other types of microscopy. They also allow for real-time observation of biological processes such as cell division or movement. Additionally, light microscopes are more accessible, easier to use, and cost-effective for routine laboratory work.

The substage on a microscope holds and controls the position of the condenser lens, which focuses and directs light onto the specimen. It helps to enhance contrast and clarity of the image by adjusting the amount and angle of light that reaches the specimen.

Yes, viruses are much smaller than bacteria and cannot be seen with the naked eye. They require a microscope, such as an electron microscope, to be visualized.

Erythrocytes, or red blood cells, can be identified under a microscope by their characteristic biconcave disk shape, lack of a nucleus, and pink/red coloration due to hemoglobin. They are typically smaller in size compared to other blood cells and appear uniform in shape when properly stained and viewed under high magnification.

You can purchase prepared microscope slides from many internet based companies including the book specialist Amazon, who stock Celestron products, or direct from specialist optics and science companies. Most of these will come in sets, as for example a 25 piece Meade selection from trees and plants or a 100 or 200 piece basic science set from Amtrope.

A biopsy is a diagnostic procedure that involves removing a small piece of tissue from the body and examining it under a microscope to identify any abnormalities or diseases.

Both compound microscope and stereo microscope typically include a base, an arm, an objective lens, an eyepiece, a stage, and a focusing knob. These common parts contribute to the basic structure and functionality of both types of microscopes.

Under a microscope, an egg appears as a round structure with a smooth surface. The outer shell is normally transparent with a dense network of calcium carbonate crystals visible. The inner yolk and albumen appear as distinct structures within the egg.

The components of a microscope typically include the eyepiece, objective lenses, stage, light source, focus knobs, and mechanical stage controls. These parts work together to magnify and illuminate the specimen being observed, allowing for detailed examination at a microscopic level.

Because an air bubble, trapped between the slide and cover plate, shows as a dark'blob' under magnification. Using a drop of water to 'seal' the slide & cover plate together excludes the air - making the specimen more visible to the user.

Depends, optic microscopes don't see much smaller than a nucleus very well, organelles such as mitochondria are seen as specks if you have a good microscope. To see more detail, you need an electron microscope (transmission or scanning), with which you can even see objects as small as viruses.
