It depends on the scope and the type of cell. The best non-electron microscope would probably be able to see some of the cell organelles. Cellular migration is a very broad statement and can mean many different things.
The study of cell migration, mostly related to high-throughput live cell screen, is a major approach employed in drug discovery and gene annotation. Basically, in vitro cell population will be allocated into each well of a culture plate while images are captured from each well at a fix time resolution. By quantifying cell behavior after inducing treatment, it is possible to estimate the cell behavior when comparing to control condition.
Depending on either in vivo or in vitro experiment.
Here I assume you are doing in vitro high-throughput high-content screening and using either phase contrast or fluorescence microscopy imaging for live cell imaging.
A short list of limitations for each microscopy imaging technology:
1. DIC or phase contrast images are difficult to process during image analysis. Also the phenotype of each cell is subjected to nonlinear light diffraction. In short word, two objects in the same size may look different under phase contrast microscope. So at least we don't use phase contrast for our experiment other than demonstration purpose.
2. Epi-fluorescence microscopy imaging is an good option for live cell imaging. However, if your sample contains nucleus staining, then phototoxicity is a serious problem. It may alter the cell migration pattern or even promote massive apoptosis. Also the strength of the laser or light source is a problem, being overexposured to laser will basically boil the cell. Autofluorescence may be a potential problem if you apply any collagen coating or introduce culture medium. But fluorescence image provides a better quality high-content data for image analysis.
3. Confocal laser is used mostly by protein and signaling process research. It is ideal for 3D imaging or visualizing a certain culture layer but image quality is highly depending on the penetration power of fluorescence staining. If the cell culture is not monolayer, you won't be able to separate each cell.

What are the differences between two-photon microscopy and confocal microscopy in terms of their imaging capabilities and applications?
Two-photon microscopy and confocal microscopy are both advanced imaging techniques used in biological research. Two-photon microscopy allows for deeper imaging into tissues compared to confocal microscopy, making it ideal for studying thick samples. Additionally, two-photon microscopy is less damaging to living samples due to its longer wavelength light. On the other hand, confocal microscopy provides higher resolution images and is better suited for imaging thin samples. Confocal microscopy is commonly used for studying cell structures and dynamics at a cellular level. In summary, two-photon microscopy is better for deep tissue imaging, while confocal microscopy is preferred for high-resolution imaging of thin samples.
How should a scientist observe the detailed structure of the cell?
A scientist can observe the detailed structure of a cell using techniques such as microscopy, including light microscopy, electron microscopy, and confocal microscopy. Staining techniques and fluorescent tags can be used to visualize specific cell components. Advanced imaging technologies, such as super-resolution microscopy and 3D reconstruction, can provide even higher resolution images of cellular structures.
What are the methods of studying a cell?
Cells can be studied using various methods including microscopy (light, electron, fluorescence), cell culture techniques, molecular techniques (PCR, sequencing), biochemical assays (ELISA, Western blot), and imaging techniques (confocal microscopy, flow cytometry). Each method provides different insights into cellular structure, function, and behavior.
Is the tonoplast visible?
The tonoplast is not visible under a standard light microscope due to its location within the cell, usually surrounded by the cytoplasm. Specialized techniques such as electron microscopy or live-cell imaging may be needed to visualize the tonoplast.
How more sophisticated microscopes have allowed scientists to advance their knowledge of cells.?
More sophisticated microscopes with higher resolution and imaging capabilities have enabled scientists to visualize smaller cellular structures, organelles, and molecules with greater detail. This has led to a deeper understanding of cell functions, processes, and interactions at the molecular level, ultimately advancing fields such as cell biology, molecular biology, and biochemistry. Additionally, advanced microscopy techniques like super-resolution microscopy and live cell imaging have provided dynamic insights into cellular dynamics and processes in real time.
What new instrument has allowed scientists to observe tbe smaller components within a cell?
The development of super-resolution microscopy has allowed scientists to observe smaller components within a cell, such as organelles and molecular complexes, at a nanometer scale resolution. This technology surpasses the limitations of conventional light microscopy, enabling researchers to explore cellular structures and processes with unprecedented detail.
Introduction in basic techniques in microscopy?
Introduction to basic techniques in microscopy involves light microscopy, laser scanning, types of dyes, the cell, electron microscopy, differential interface microscopy, histological stains and histochemical stains.
Which technique can show that the cell membrane has two layers?
The technique that can show that the cell membrane has two layers is electron microscopy. By using transmission electron microscopy (TEM), the phospholipid bilayer structure of the cell membrane can be visualized, showing the double-layered arrangement of phospholipid molecules.
What should a scientist do to determine the shape of human muscle cells?
To determine the shape of human muscle cells, a scientist should use microscopy techniques, such as light microscopy or electron microscopy, to visualize the cells at a high resolution. Staining methods can enhance cellular structures and highlight specific features. Additionally, three-dimensional imaging techniques, like confocal microscopy, can provide more detailed insights into the cell's morphology. Finally, analyzing the gathered images with software can help quantify and confirm the shapes observed.
What are the advantages and disadvantages of Confocal microscopy?
Confocal microscopy offers several advantages, including improved optical resolution and the ability to obtain three-dimensional images of specimens by using a focused laser beam to scan across the sample. This technique enhances contrast by eliminating out-of-focus light, making it ideal for imaging thick samples. However, disadvantages include the complexity and cost of the equipment, as well as longer acquisition times compared to traditional microscopy methods, which may limit its use for live-cell imaging. Additionally, the technique may require specialized sample preparation and staining, which can complicate the workflow.
How could a scientist examine a cell?
A scientist can examine a cell using various techniques such as light microscopy, electron microscopy, immunofluorescence microscopy, or molecular techniques like PCR and sequencing. These methods allow scientists to visualize the structure, composition, and behavior of cells at different levels of detail.
Why are transmission positron microscope and acoustic microscope important for understanding how living cells function?
Because only the Transmission Position Microscopes and the Acoustic Microscopes are able to magnify living specimen while the Electron Microscope has the major disadvantage of only being able to magnify dried, frozen, and dead specimen. We also wouldn't be able to learn much about living cells.
