Viruses are incredibly small - much smaller than the smallest of bacteria, even though many millions of bacteria could fit on a pinhead. Therefore viruses can only be seen with the help of a very powerful microscope such as a scanning ellectron microscope.
Yes, bacteria can be seen under a light microscope as they are larger than viruses. However, viruses are much smaller and cannot be seen with a light microscope. Specialized electron microscopes are required to visualize viruses.
No, viruses are generally much smaller than cells they infect. Viruses are considered to be submicroscopic in size and are typically measured in nanometers, while cells are much larger and can be seen with a microscope.
Viruses cannot be seen under a light microscope as they are too small. However, techniques like electron microscopy and immunofluorescence can be used to visualize viruses. By tagging viruses with fluorescent markers or using more powerful electron microscopes, researchers can study viruses in greater detail.
Bacteria and viruses are too small to be seen by the naked eye because they are microscopic in size, typically measuring in nanometers or micrometers. Their size is below the resolution limit of the human eye, which is why we require microscopes to visualize them.
Viruses are much smaller than the resolution limit of a light microscope, which is about 200 nanometers. Most viruses are around 20-400 nanometers in size, making them too small to be seen with a light microscope even at high magnifications like 100x. Specialized techniques like electron microscopy are needed to visualize viruses.
they certainly can be seen
Viruses are too small to be seen directly with a light microscope.Can be seen when it's examined under an electron microscope
Bacteria are much larger than viruses and can be seen under a light microscope, which was available in the 17th century. In contrast, viruses are much smaller and can only be seen with the invention of the electron microscope in the 20th century, leading to their discovery in 1938. This difference in size and technology needed for visualization explains the lag in discovery between bacteria and viruses.
Viruses are too small for van Leeuwenhoek to have seen with his simple microscope.
Viruses are too small, and can't be seen in an optic microscope.
Viruses cannot be seen with a compound light microscope as they are too small, typically ranging from 20 to 400 nanometers in size. Specialized electron microscopes, such as transmission electron microscopes, are used to visualize viruses due to their high magnification capabilities.
Viruses could not be seen because the resolution and magnification was not good enough until 1938 when Ernst Ruska developed the electron microscope.
Only the largest of viruses (e.g. Pox viruses) can be seen with a good light microscope (albeit with poor detail). Viruses usually can only be seen by electron microscopy. [2nd year Dental student, Naser]

they are able to multiply, which could be seen as a form of reproduction
Most viruses cannot be seen by light microscopy because they are much smaller than the wavelength of visible light, making them invisible to the human eye when using this type of microscope.
if your talking about the cell then they can be any shape
