Plasma membranes are not dense enough to be seen clearly with a transmission microscope without some sort to staining procedure. A phase-contrast microscope (also light microscope, but with slightly different optics) is the usual tool, especially for cultured cells.

What type of opaque object keeps light focused and scatters wavelengths of visible light for the human eye to see?
It will be right to say that only principles of light microscopy keeps light focused and scatters wavelengths of visible light for the human eye to see.
Where does the light reaction of photosynthesis occur?
In the plant's leaves or wherever the plant has chloroplasts. More specifically, the light reactions take place on the thylakoid membranes in the chloroplasts. The light reactions can also take place on the plasma membranes of the cells (as with cyanobacteria) or in other plastids.
Is cytoplasm visible with a light microscope?
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.
Why is the mitochondria and chloroplast not visible under a micro-scope?
Microscopes have been crucial for understanding organelles. ... However, most organelles are not clearly visible by light microscopy, and those that can be seen (such as the nucleus, mitochondria and Golgi) can't be studied in detail because their size is close to the limit of resolution of the light microscope.
An advantage of fluorescence microscopy over staining techniques is that?
fluorescence microscopy can be used wit any light microscope

What type of microscopy does not use light?
Electron microscopy; Scanning Electron Microscopes (SEM) and Transmission Electron Microscopes (TEM). The vacuum required for electron microscopy to work correctly precludes the observation of living organisms. Biological samples must be dried then coated with a conductive metal.
What is the cell membranes appearance?
Bio membranes are not visible under the light microscope because their plasma thickness is below the resolving power of the microscope. Under electron microscope bio membranes appear to be trilaminar or tripartite. There is an electron dense or dark layer on either side of middle electron transparent layer. Freeze etching technique has shown that a membrane possesses particles of different sizes.
Does light microscopy offer better magnification than electron microscopy?
No

A visible sunbeam is an example of?
Visible light is an example of electromagnetic radiation.NO it is electromagnetic energy.actually it electromagnetic waves =P
Is light a plasma?
plasma is electricity and light but light is not a plasma
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.
Is lightning a plasma?
Well, the path in which the visible portion of lightning takes is plasma. But plasma is a gas. An ionized gas. So the flash of light you see is static electricity from the clouds jumping through that ionized gas (plasma) to the earth.I have a master's in EE. I'm creatable. :)
An advantage of fluorescence microscopy over staining techniques is that?
fluorescence microscopy can be used wit any light microscope
