When examining an onion under a microscope labeled with specific markers, one can observe the different cell structures and components of the onion, such as the cell walls, nuclei, and cytoplasm. The markers help to highlight and distinguish these structures, allowing for a more detailed and precise analysis of the onion cells.
When examining onion cells under a microscope, key characteristics observed include a rectangular shape, a cell wall, a large central vacuole, and a distinct nucleus.
When examining an onion cell under a microscope, key features that can be observed include the cell wall, cell membrane, cytoplasm, and nucleus. These features are labeled for identification based on their distinct shapes, sizes, and locations within the cell.
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.
The specific structure within an animal cell that is not labeled in typical diagrams is the glycocalyx.
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.

The fine focus knob is the labeled part of the microscope that would most likely be adjusted to bring the specimen into sharp focus.

The structure of an onion cell labeled under a microscope consists of a cell wall, cell membrane, cytoplasm, nucleus, and vacuole. The function of an onion cell is to store nutrients, provide structure and support, and facilitate cellular processes such as growth and reproduction.
Immunofluorescence is a technique allowing the visualization of a specific protein or antigen in cells or tissue sections by binding a specific antibody chemically conjugated with a fluorescent dye such as fluorescein isothiocyanate (FITC). There are two major types of immunofluorescence staining methods: 1) direct immunofluorescence staining in which the primary antibody is labeled with fluorescence dye, and 2) indirect immunofluorescence staining in which a secondary antibody labeled with fluorochrome is used to recognize a primary antibody. Immunofluorescence staining can be performed on cells fixed on slides and tissue sections. Immunofluorescence stained samples are examined under a fluorescence microscope or confocal microscope

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 word "labeled" refers to something that has been given a descriptive tag or marking to identify it or provide information about it. It can also indicate that something has been categorized or defined in a specific way.
