DNA in the form of chromosomes and sister chromatids (which are identical replicated chromosomes).
The cytoplasm is somewhat clear when looking through a light microscope. However you can see where the cytoplasm is. You can see cell walls and cell membranes through a light microscope, the spaces in between these lines is cytoplasm.
You can see chloroplasts and a nucleus under a light microscope.
Under a light microscope, you can observe small objects such as cells, bacteria, and other microorganisms. The microscope uses light to magnify these objects, allowing you to see them in detail.
You can examine the cell under a light microscope. Eukaryotic cells have nuclei, and these should be visible under a light microscope.
An electron microscope has a much higher magnifying power and resolution than a regular light microscope. One can visualize molecules and even atoms using an electron microscope. This is not possible with a light microscope
Chromosomes, made up of DNA and proteins, are visible under a light microscope as a cell divides. They appear as distinct structures within the cell during stages such as prophase, metaphase, anaphase, and telophase of mitosis.
The organelles in a cheek cell that are not visible under a light microscope are the ribosomes. These organelles are responsible for protein synthesis.
Common types of microorganisms that can be seen under a light microscope include bacteria, yeast, algae, and protozoa. These microorganisms are relatively larger and can be observed with a brightfield microscope at higher magnifications. Viruses, which are much smaller, typically require an electron microscope for visualization.
A spectrophotometer is the instrument used to measure the absorption spectrum of a substance. It measures the amount of light absorbed by a sample at different wavelengths, providing information about the substance's chemical composition.
The specimen being viewed under a microscope is typically referred to as a sample or a slide. It is the material or substance that is being examined or analyzed using the magnification and resolution capabilities of the microscope.
That is when the DNA is condensed, at which time it is called chromosome.
Yes, mycoplasmas can be studied with a light microscope, but they are quite small, so they may be difficult to observe due to their size. Staining techniques can be used to help visualize mycoplasmas under a light microscope. Transmission electron microscopy is often used for more detailed studies of mycoplasmas.
