Some organelles, like ribosomes, are too small to be resolved using a light microscope because their size is close to the limit of resolution of light. Additionally, some organelles may not have distinctive features or contrast with the surrounding cytoplasm, making it difficult to visualize them clearly under a light microscope.
The nucleus is the most noticeable organelle in a eukaryotic cell under a microscope due to its size and distinct structure. It appears as a large, round structure typically located in the center of the cell.
The diagram that represents a cell organelle that can absorb iodine stain and be seen with the low power of a compound light microscope is the nucleus. The nucleus absorbs the iodine stain and becomes visible under the microscope due to its high DNA content, which binds with the stain.
Ribosomes are organelles that are too small to be seen with a light microscope as they are typically smaller than the resolution limit of light microscopes, which is around 200 nanometers. Ribosomes are essential for protein synthesis in cells.
Flagella are typically only visible through an electron microscope due to their small size, which is on the order of a few micrometers. Light microscopes do not have the resolution necessary to clearly visualize structures at this scale.
An electron microscope is typically used to view organelles, as it provides a higher resolution and can visualize smaller structures compared to a light microscope. Transmission electron microscopes (TEM) are often used to view organelles at high magnifications.
We can't see a mitochondria
Light microscope cannot be used. An electron microscope houl b used
The organelles in a cheek cell that are not visible under a light microscope are the ribosomes. These organelles are responsible for protein synthesis.

That is when the DNA is condensed, at which time it is called chromosome.

Bacteria that cannot be seen by a light microscope are typically smaller in size and require an electron microscope for visualization. Examples include species of Mycoplasma, Chlamydia, and Borrelia burgdorferi (cause of Lyme disease).
Viruses are too small to be seen with a light microscope because they are smaller than the wavelength of visible light. This means that light cannot pass through them or be reflected off of them, making them invisible under a light microscope.
The microscope that is used to see internal structures of cells in a natural state is the compound light microscope. The microscope has a lens and light that allows it to see the internal structures of a cell clearly.
Viruses. They are smaller than the average wavelength of light and as such are not viewable unless an electron microscope is used.
Ribosomes are organelles that are too small to be seen with a light microscope as they are typically smaller than the resolution limit of light microscopes, which is around 200 nanometers. Ribosomes are essential for protein synthesis in cells.
