A bright field microscope can be used to view?
A bright field microscope can be used to view stained samples that absorb light, making them appear darker against a bright background. It is commonly used in biology labs to view cells, bacteria, and tissue samples.
What do nucleic acids look like under microscope?
Under a microscope, nucleic acids appear as long, thread-like structures. Their specific appearance depends on how they are stained, but typically they will appear as thin fibers or strands within the cell. Nucleic acids themselves are too small to be seen without special techniques like electron microscopy.
What does cocci look like?
Circle shaped looking bacteria.
What shape does streptococcus look like under a microscope?
Streptococcus bacteria usually appear as small, round or ovoid cells when viewed under a microscope. They typically grow in chains or pairs, giving them a characteristic elongated or twisted appearance. These bacteria are gram-positive, meaning they will appear purple when stained with Gram stain.
Assume you stain Bacillus by applying malachite green with heat and then counterstaining with safranin Through the microscope the green structures are?
Bacillus cells stained with malachite green and safranin will appear red under the microscope due to the counterstaining with safranin. Malachite green primarily stains the spores of Bacillus while safranin stains the rest of the cell, resulting in red-stained vegetative cells and green-stained spores.
What colour are cheek cells?
methelyn blue
What colour does the starch grain be?
Starch grains are typically colorless or white when observed under a microscope. The color may appear dark if stained with certain dyes for visualization purposes.

A well stained leaf peel mount when observed under the high power of a microscope shows nuclei in?
A well-stained leaf peel mount observed under high power of a microscope will show nuclei in the plant cells. Nuclei in plant cells appear as darkly stained, round or oval structures within the cytoplasm of the cell, providing important genetic and regulatory functions for the plant cell.
How does its appearance differ form the rod stained with methylene blue?
A rod stained with methylene blue will appear blue under a microscope due to the dye binding to cellular components like DNA. In contrast, an unstained rod will appear colorless or slightly transparent. Staining with methylene blue helps to enhance cellular structures for better visibility and analysis.

How can you observe a white blood cell in a light microscope?
White blood cells can be observed in a light microscope by preparing a blood smear, staining the cells with a dye like Wright's stain or Giemsa, and then viewing them under high magnification. The cells will appear as small, irregularly shaped cells with a dark-stained nucleus and a lighter-stained cytoplasm.
If one stained a gram-positive cell only with safranin?
If a gram-positive cell is stained only with safranin, it would likely appear pink or red under a microscope. This is because safranin is a counterstain used in the Gram staining procedure to colorize gram-negative bacteria, whereas gram-positive bacteria retain the crystal violet primary stain and appear purple.
What does the root chrom mean?
The root "chrom" refers to color. It is commonly found in words related to color or pigmentation, such as "chromosome" which refers to the structures that contain genetic material and are typically stained to appear visible under a microscope.
