It is easier to view because it already has a light source. *Basically you can not use living tissue with Electron Microscopes, but only Light compound ones. "Because electron microscopes require a vacuum to operate samples must e preserved & dehydrated before they are placed inside the microscope. Meaning that living cells cannot be observed with electron microscopes, only with the light ones."
Some disadvantages of phase contrast microscopy include lower resolution compared to other techniques such as fluorescence microscopy, difficulties in distinguishing different refractive index structures that are similar, and the requirement for careful alignment and calibration for optimal results.
A fluorescence microscope consists of a light source to excite fluorophores, a filter cube to select excitation and emission wavelengths, a dichroic mirror to reflect excitation light toward the specimen, a objective lens to focus light onto the sample, and a detector to capture emitted fluorescence. These parts work together to visualize fluorescently labeled structures in biological samples.
fluorescence microscopy allows for specific targeting of molecules or structures within a sample using fluorescent dyes or proteins, resulting in enhanced specificity and sensitivity compared to traditional staining techniques. Additionally, fluorescence microscopy enables dynamic imaging of live cells or tissues in real-time, providing insights into cellular processes and behaviors that cannot be captured by staining methods.
Yes, you can observe viable cells with a fluorescence microscope by using specific dyes or probes that are taken up by living cells. These dyes can interact with intracellular components such as DNA or proteins, allowing you to visualize the cells under the microscope. It is important to use appropriate staining techniques and controls to ensure accurate interpretation of the results.
The easiest microscope to use for observing cell membranes is a fluorescence microscope. This type of microscope allows for the visualization of specific proteins or lipids in the cell membrane by using fluorescent dyes or tags, which can highlight structures that may be difficult to see with traditional light microscopes. Fluorescence microscopy also provides better contrast and resolution for cellular components, making it ideal for studying dynamic processes in living cells.
Ernst Abbe invented the fluorescence microscope in 1873 its magnification is up to 100x max which is suitable for this microscope.
Cannot provide spatial resolution below the diffraction limit of specific specimen features http://www.microscopyu.com/articles/fluorescence/fluorescenceintro.html
advantage: cheap, multiple lenses, can look at live specimens. disadvantage: poor resolution, poor magnification

The fluorescence microscope was invented in 1911 by German physicist Otto Heimstädt. He discovered that certain dyes could absorb light at one wavelength and emit it at another, allowing for the visualization of fluorescently-labeled structures.

The fluorescence microscope was invented to allow scientists to visualize and study the internal structure and dynamics of cells and tissues. It relies on the principle of fluorescence to enhance contrast between specific structures, such as proteins or organelles labeled with fluorescent dyes, making them easier to observe under the microscope. This tool has revolutionized biological research by enabling researchers to study complex biological processes at the molecular level.
I'm unable to see images or arrows directly. However, if you describe the microscope or provide details about its features, I can help you identify its type, such as a light microscope, electron microscope, or fluorescence microscope.

A light microscope, specifically a fluorescence microscope, is often used to see intracellular details in living cells. Fluorescence microscopy allows specific structures or molecules within the cell to be labeled with fluorescent dyes or proteins, which can then be visualized under the microscope. This enables researchers to study dynamic processes within living cells in real-time.
