How do chemical stains making microscopes more useful?
Chemical stains make light microscopes more useful by showing specific structures in a cell.
How do chemical stains make light microscopes more useful?
Chemical stains provide contrast with which to view dintinctly different portions of cell structures.
What used to produce an enlarged image of a cell?
Microscopes are used to produce an enlarged image of a cell. Light microscopes use visible light to magnify the image, while electron microscopes use a beam of electrons to achieve higher magnification and resolution. Special staining techniques may also be used to highlight specific structures within the cell.
What cell parts are not visible with 400x microscope?
Cell organelles such as ribosomes, small vesicles, and some components of the cytoskeleton are not visible with a 400x microscope. These structures are smaller than the resolution limit of light microscopes at that magnification.
How do you identify a prokaryotic cell?
It can be done by simple light microscopes. For example Bacteria can be seen under microscope with some stains. But you can not characterize the exact group or nature prokaryote by microscopes for which we actually need genetic data or the pattern of their DNA.A prokaryote cell is identified by its cell wall being gram positive or negative.By the absence of nuclear membrane. By the ways they obtain energy. By their special methods of movement.
Why can't certain cell structures be seen under light microscopes?
Certain cell structures, such as organelles like ribosomes and lipid droplets, are too small to be resolved by light microscopes due to their limited resolving power (around 200 nm). These structures require higher resolution techniques like electron microscopy to be visualized effectively.
How do chemicals stains light microscopes more useful?
Chemical stains make light microscopes more useful by showing specific structures in a cell.
Why are electron microscopes better than light microscopes when looking at cells?
Electron microscopes have higher resolution and magnification than light microscopes, allowing for the visualization of smaller structures within cells, such as organelles and macromolecules. Additionally, electron microscopes use electron beams, which have shorter wavelengths than visible light, enabling them to capture finer details of cell structures.

What is a feature transmission electron microscope has but not light microscopes?
The ability to achieve much higher magnifications and resolutions than light microscopes due to a much shorter wavelength of electrons. Transmission electron microscopes can visualize structures at the atomic level, which is not possible with light microscopes.

Light microscopes use visible light to magnify the image, while electron microscopes use a beam of electrons to achieve higher magnification and resolution. Special staining techniques may also be used to highlight specific structures within the cell.
How would an algae cell appear under different types of microscopes?
Under a light microscope, an algae cell may appear as a green, oval-shaped structure with chloroplasts. Under a scanning electron microscope, the cell would show more details of its surface structure. Under a transmission electron microscope, the internal structures of the cell, such as the nucleus and mitochondria, would be visible in high resolution.
What instrument do scientist use to look at cell?
Scientists use microscopes to look at cells. There are different types of microscopes, such as light microscopes and electron microscopes, that allow scientists to observe cells at various levels of detail. These instruments magnify the structures within cells, enabling researchers to study their composition and functions.
What can you see by light microscopes in plant and animal cell?
Depending on which power you are using, you should be able to see all the major cell structures using a light microscope. This includes the nucleus, mitochondria, chloroplasts (plant only), etc.
Are cells discovered using electron microscopes?
Yes, cells can be visualized and discovered using electron microscopes due to their high magnification and resolution capabilities. Electron microscopes can reveal details at the nanometer scale, allowing for the visualization of organelles and structures within cells that may not be visible with light microscopes.
Who was the first person to see a cell light structures under the microscope?
