individual cells are practically transparent, that is, light will pass directly through them and when viewed under a normal light microscope, almost nothing will have enough contrast for you to descern the different structures. Staining gives colour to the sample, increasing contrast between the cells and the surroundings, hence making it easier for you to observe them under the microscope. Usually stains do not simply give colour to the cell in general but bind to specific structures within the cell, making it easier to view specific organelles. However, staining is not required for all types of microscopy techniques. Some microscopy techniques required a completely different method of sample preparation, such as in electron microscopy.

What type of microscope are used to study cells?
Biologists typically use light microscopes to study cells. These microscopes use visible light to illuminate the sample and produce magnified images of cells. Other types of microscopes, such as electron microscopes, can also be used to study cells at higher magnifications and more detailed levels.
Why do biologists use dividing cells to determine the number of chromosomes in an organism?
Biologists use dividing cells to determine the number of chromosomes in an organism because chromosomes are most visible and distinct during cell division. By observing dividing cells under a microscope, biologists can count the number of chromosomes present, which provides information about the genetic makeup of the organism.
What type of scientists use a microscope?
Scientists such as biologists, microbiologists, and material scientists use microscopes to study small organisms, cells, tissues, and materials at a microscopic level. Microscopes help these scientists observe and analyze the intricate structures and functions of their subjects.
Why do biologists use the microscope?
Biologists use microscopes to observe and study microscopic organisms or structures that are too small to be seen with the naked eye. Microscopes allow biologists to magnify and visualize tiny details, helping them to better understand the biological world at a cellular and molecular level.
Why do many biologists consider the microscope as one their most valuable tools?
Biologists consider the microscope one of their most valuable tools because it allows them to study cells, microorganisms, tissues, and other biological structures at a very detailed level that would otherwise be impossible to see with the naked eye. Microscopes enable biologists to make important discoveries in fields such as microbiology, genetics, and anatomy.
In order to study the internal ultrastructure of cells what should biologists use?
Transmission Electron Microscopy
When biologists wish to study the internal ultrastructure of cells what kind of microscope would they use?
a transmission electronic microscope.

What do cell biologists use a TEM to study?
Cell biologists use a transmission electron microscope (TEM) to study the internal structures of cells. This powerful microscope allows them to visualize organelles, membranes, and other subcellular structures at very high resolution. TEM is especially useful for studying cellular ultrastructure and identifying organelles in detail.

Why do biologists use different stains?
A lot of tissue is the same colour and density: have you ever look at glass under water, it is much the same thing. Staining things makes different things take on colour and they can be seen much more clearly. I believe the first medical staining was done by Doctor Erhlich in working with the tuberculosis bacterium.
Biologists who employed the microscope in their work?
Anton van Leeuwenhoek invented microscopy, and made the first modern microscopes. If you are trying to ask for the names of present-day biologists who employ the microscope in their work, the answer is "all of them." Microscopy is so important to biology that all biologists have microscopes and use them frequently.

What are microscopes used?
Microscopes are used to see things too small for the naked eye. They are used to look at cells from plants and animals and many other things that our eyes can't see. Geologists use them to study rock samples. Biologists use them to examine cells, bacteria, and the structures of bones and tissues. Doctors and forensic pathologists use them to study the changes in tissues that can cause illness or death. Manufacturing chemists use microscopes to study how chemicals interact. Engineers use microscopes, electron microscopes and x-rays to study the form and structure of materials, and how they react to physical and chemical changes.
