∙ 10y agoAssuming there actually is a nucleus in the cell (it isn't undergoing cell division or anything), the nucleus is actually transparent and you see it with dyes that target it. You might be able to see it if it isn't transcriptionally active, when the DNA is condensed inside it.

∙ 10y agoIf a nucleus is not visible through a microscope, it might be due to several reasons, such as its size being below the resolution limit of the microscope, its transparency, or the sample not being stained appropriately to make it visible. Additionally, if the nucleus is not in the field of view or if the microscope is not focused correctly, it may also be difficult to observe.
In some cases, nothing can be seen through a microscope if the sample is too thick or dense for light to pass through effectively. Additionally, if the sample is not mounted properly or if the microscope is not focused correctly, it can also result in not being able to see anything. Proper sample preparation and microscope settings are important for clear visualization.
A light microscope uses lenses to bend and focus light rays passing through a specimen, magnifying the image. The specimen interacts with the light passing through it, which is then transmitted through a series of lenses to produce a magnified image that can be viewed through the eyepiece.
No, proteins with a nuclear localization signal require energy to actively transport through the nuclear pore complex into the nucleus. They are not able to enter the nucleus passively. The binding and translocation through the nuclear pore are facilitated by specific transport receptors and require energy in the form of GTP hydrolysis.
As you close the diaphragm by moving it under the stage of a microscope, less light is able to pass through the specimen. This results in a decrease in light intensity, making the image appear dimmer. Adjusting the diaphragm helps control the contrast and brightness of the image.
Specimens need to be thin to allow light to pass through them and be able to observe details and structures at a cellular or subcellular level. Thicker specimens would block the light and hinder the ability to visualize the specimen clearly under a microscope. A thin specimen also helps to reduce scattering and distortion of the image.
With a less stronger microscope the nucleus ,cell membrane and cytoplasm are visible,but in plant cell cell wall and chlorophalast
Without vitreous humor, the eye's shape and structure would be compromised, resulting in loss of support and increased risk of retinal detachment. Vision may also be affected due to changes in the eye's ability to focus light onto the retina.
Yes why wouldnt she be able to?
high power
the reason you cant see is because you are angling your eye wrong
Under a compound light microscope, you would not be able to see specific organelles like the lysosomes, peroxisomes, endoplasmic reticulum, and Golgi apparatus in an onion cell stained with iodine. These organelles are typically smaller and/or transparent, making them difficult to visualize with this type of microscope.

The opening in the stage of a microscope allows light to pass through to illuminate the specimen from below. This illumination is essential for viewing the specimen clearly and in detail under the microscope.
Without a nucleus, the plant cell would not be able to control its genetic information or carry out essential cellular functions. It would not be able to synthesize new proteins or replicate its DNA, leading to impaired growth and survival. The cell would lack direction and regulation, ultimately resulting in its inability to function properly.
We wouldnt be able to make any sort of proteins
no it doesnt if it did it wouldnt be able to be made.
You wouldnt be able to do research online or watch t.v.
