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.
What else can I help you with?
How does it appear under the microscope?
Under the microscope, objects are magnified to be visible in more detail than with the naked eye. Light microscopes use visible light to magnify samples, allowing for observation of cellular structures and organisms. Electron microscopes use a beam of electrons for higher resolution imaging at the nanoscale level.
Can Viruses be seen with a light microscope.?
Viruses are too small to be seen directly with a light microscope.Can be seen when it's examined under an electron microscope
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.
Does urine glow under a black light?
Yes, urine can glow under a black light due to the presence of certain compounds such as phosphorus and riboflavin that fluoresce under ultraviolet light.
What instrument is used to prepare a slide of xylem and phloem tissue for observation with a compound light microscope?
A microtome is commonly used to cut very thin slices of the xylem and phloem tissue, which are then transferred to a glass slide to be observed under a compound light microscope. Staining techniques can also be applied to enhance contrast and make the structures more visible.
Can cell structures be seen under light microscopes?
Large cell structures such as the nucleus and mitochondria can be seen under the light microscope if they are properly stained. In addition, chromosomes and centromeres can be seen during cell division.
How do microscopes get illumination?
The light under the platelet.
Where are Details of cellular structures are most easily seen?
Details of cellular structures are most easily seen under a microscope, particularly using light microscopes or electron microscopes. Light microscopes can reveal larger organelles like the nucleus and mitochondria in stained specimens, while electron microscopes provide much higher resolution, allowing for visualization of smaller structures like ribosomes and the endoplasmic reticulum. Additionally, advanced imaging techniques such as fluorescence microscopy enable researchers to observe specific cellular components in detail.

Light microscopes use visible light to magnify samples, allowing for observation of cellular structures and organisms. Electron microscopes use a beam of electrons for higher resolution imaging at the nanoscale level.
The best light microscopes can magnify images up to how many times?
The best light microscopes can magnify images up to 1500 times under optimal conditions using oil immersion lenses. This allows for detailed observation of cellular structures and processes.
What unit of measerment is used for objects seen under the microscopes?
Objects seen under microscopes are typically measured in micrometers (µm), also known as microns. This unit is commonly used for measuring the size of cells, bacteria, and other tiny structures visible under a microscope.
How do chemical stains make light microscopes more useful?
Chemical stains provide contrast with which to view dintinctly different portions of cell structures.
Does a specimen have to be moving and respiring to be able to be seen under a light microscope?
No, I used light microscopes in my science class and it worked very well.
Does a microscope only use light?
Optical microscopes use only light to observe the item under magnification. Electron microscopes use beams of electrons that are captured by sensors, and use digital processing to generate an image based on the pattern of detected electrons.
What is the chemical used in microscopes to make the specimen visible?
In standard light microscopes, no chemical is used; subjects are observed by light projected from underneath the stage, which light up whatever is on top. Most microscopes allow amount of light to be adjusted (usually both the power of light projected and an aperture to control the exposure), and at lower settings things that are "harder to see" with more light become visible. Occasionally, under regular circumstances whatever your studying, some kind of bacteria, for instance, may be difficult to see. In this case, you might stain the bacteria, especially to highlight certain aspects of it (cell wall, for example). However, again, this is not a chemical in the microscope but with the subject itself - the microscope is the same as it always was.
