WebWhat parts of a cell can be seen with a light microscope? Note: The nucleus, cytoplasm, cell membrane, chloroplasts and cell wall are organelles which can be seen under a … WebYou can see the nuclei stained with a dark blue (because Methylene Blue stains strongly with DNA). The cell membrane acts like a balloon and holds all the parts of a cell, like a nucleus, cytosol, and organelles inside. The right image is at a higher magnification. You can also see some small rod-shaped bacteria.

WebWhat microscope can see DNA? To view the DNA as well as a variety of other protein molecules, an electron microscope is used. Whereas the typical light microscope is only limited to a resolution of about 0.25um, the electron microscope is capable of resolutions of about 0.2 nanometers, which makes it possible to view smaller molecules. WebNo, you can not see the individual double-strand DNA with a light microscope. The width of the double-strand DNA is about 2 nm, which is beyond the resolution of the light …
WebLight microscopes use a system of lenses to magnify an image. The power of a light microscope is limited by the wavelength of visible light, which is about 500 nm. The most powerful light microscopes can resolve bacteria but not viruses. To see anything smaller than 500 nm, you will need an electron microscope. WebDNA cannot be seen in the regular compound microscope. But DNA can be seen with the help of more advanced methods like electron microscopy and atomic force microscopy. …
