What else can I help you with?
Bacteria were first seen in 1683 but viruses were not seen until 1938why?
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.
Why are viruses considered?
they are able to multiply, which could be seen as a form of reproduction

Can viruses be seen with a microscpe?

Can Viruses be seen with a light microscope.?
Viruses are too small to be seen directly with a light microscope.Can be seen when it's examined under an electron microscope
Why might HIV not cause symptoms right away?
Many bacteria and viruses need time to multiply before any signs and symptoms can be seen.
Why did Robert Hooke's not include viruses in his book?
Viruses are too small, and can't be seen in an optic microscope.
Did leeuwenhoek observe protoza and viruses?
Viruses are too small for van Leeuwenhoek to have seen with his simple microscope.
Can viruses be seen with a compound light microscope How can they be seen?
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.
Are viruses seen under an 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]
What cell structure could not be seen until the electron microscope was invented?
The cell structure that could not be seen until the invention of the electron microscope is the organelle called the mitochondrion. Mitochondria are responsible for producing energy for the cell through a process called cellular respiration.
Can you see bacteria with viruses under 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.
