What is the definition of the term fluorescence microscopy?
The term "fluorescence microscopy" is a type of light microscopy in which the specimen is irradiated at wavelengths that excite fluorochromes. In medicine, it is used to detect antigens.
Simple staining is often necessary to improve contrast in what microscope?
The type of microscopy that uses chemical stains to add color and increase contrast is light. The type of microscope that can be used to observe very small surface details is called a scanning electron.
What is darkfield microscopy used for?
To view unstained cells.
Can bromthymol blue be used as a stain for a cheek cell in compound microscopy?
Yes
What is the function methylene blue solution in the preparation of cheek cells slide?
Methylene Blue, in this situation, is being used as a microscopy stain. Microscopy stains are used to allow for particular characteristics of cells to be observed in greater detail or to make them easier to see.
The two most common methods for visualizing live cells are phase-contrast microscopy and differential interference contrast microscopy?
perhaps
What concept of microscopy deals with the ability of the specimen to stand out against its background?
Contrast
What is the difference between phase-contrast microscopy and bright-field microscopy?
Phase-contrast microscopy is the observation of internal structures of living microbes where as bright field microscopy is the observation of killed stained specimens and naturally colored live ones.
What is the importance of contrast in microscopy?
There are many objects that are difficult to see with a microscope. The purpose of the contrast is to make it easier to see specimens that are transparent and unstained.
Which of the following would be best observed for a bacterial cell using phase contrast microscopy?
Motility
Where would phase contrast microscopy would improve image quality?
whenever you're looking at a wet mount you want to use phase contrast
Which type of microscopy is used for colorless specimens?
Transmission electron microscopy
Which works best with phase contrast microscopy wet mount or hang drop?
wet mount slide
What is the definition of the term fluorescence microscopy?
The term "fluorescence microscopy" is a type of light microscopy in which the specimen is irradiated at wavelengths that excite fluorochromes. In medicine, it is used to detect antigens.
What type of slide works best with phase-contrast microscopy?
Hanging drop can be observed for longer periods of time without drying out.
An advantage of fluorescence microscopy over staining techniques is that?
fluorescence microscopy can be used wit any light microscope
Simple staining is often necessary to improve contrast in what microscope?
The type of microscopy that uses chemical stains to add color and increase contrast is light. The type of microscope that can be used to observe very small surface details is called a scanning electron.
