Well, all of the kingdoms existed, they just hadn't been discovered yet. However, the ones that had been discovered were plant and animal.
Bacteria and protists are microscopic, so without a microscope you cannot see them, and fungi were thought to be plants. Scientists didn't have the technology (the microscope) to be able to see the differences in the functions and structures of the fungi kingdom and the plant kingdom.

Why must the underside of the microscope slide be dry before being placed on a microscope?
So the liquid doesn't damage the lenses
What is a Specimen Smaller Than 0.2 Micrometers Must Be Completely Dried Out Before Being Studied Using This Type Of Microscope?
Electron Microscope
Why must a specimen be thin in order to be viewed under the microscope?
Because light must pass through it.
Why must a specimen be thin to be viewed under the microscope and why are they sometimes stained with dyes?
To see them better
How must samples be prepare for observation by electron microscope?
They must be preserved and dehydrated. Once this is accomplished, put the specimen onto a slide, and then the slide is ready to be viewed under the microscope.

Why must a specimen be very thin to be viewed under a light microscope?
Light microscope works because light goes *through* your specimen. So if the specimen is too thick, then light won't shine through, and you won't see anything.
Why should a specimen to be viewed under the microscope must be thin?
Body tissues and bones are opaque beyond a certain thickness. To view fine structures, exceedingly thin samples will be translucent, revealing cell and tissue structure.
Is AIDS an organism that can be seen under a microscope?
AIDS is the disease caused by the virus called HIV. It can not be seen under a light microscope (as one in the class lab) but you must use an electron microscope as they are very tiny.
What are three limitations of a electron microscope?
Objects must be viewed in a vacuum. So nothing living.All images are planar, must use fancy shadow trick with vapourized metal to get 3D.Needs power.
What can be viewed with a light microscope?
Anything that is smaller than the wavelength of light, thatmeans that it is smaller than light and therefore is not visible, at all, to know it exists an electron microscope must be used which captures a reflection of the object a scanning electron microscope uses a computer to make the image
How can you summarize Hooke's observations of the cork under a microscope?
umm... you must be a 7th grader 2
Compare the process used to produce a TEM and an SEM?
The process used to produce TEM will cut cells and tissues in to ultra-thin slices so that they can be viewed under the microscope. However, the ones on SEM do not need to be cut as they can easily be visualized.
