Because, it is too small to see with the naked eye.
we need microscope to see unicellular organism because they are very small
Organism that have one cell (single celled) are so small, you would need a microscope to see them. So, orchids are multicellular.
Yes. One celled or unicellular organisms are so small you would need a strong microscope to see one.
To calculate the size of the organism, you would need to know the magnification of the microscope being used. Comparing the field diameter at 400x magnification with the actual size of the organism would give you the scale factor to determine the organism's size. For example, if the field diameter at 400x is 0.5 mm, and the actual size is 50 micrometers, then the organism is 10 times smaller than the field diameter.
It can be done by simple light microscopes. For example Bacteria can be seen under microscope with some stains. But you can not characterize the exact group or nature prokaryote by microscopes for which we actually need genetic data or the pattern of their DNA.A prokaryote cell is identified by its cell wall being gram positive or negative.By the absence of nuclear membrane. By the ways they obtain energy. By their special methods of movement.
Because these organisms are too smaller to be observed directly.
Prokaryotic cells are smaller and lack a nucleus and other membrane-bound organelles, making them difficult to see with the naked eye. A microscope is necessary to magnify and visualize these tiny organisms, allowing for detailed observation of their structure and characteristics.

Liquids and gases expand inside a vacuum, so the organism's shape would be destroyed..
If you need a microscope to see a human then yes, otherwise no.

Depends, optic microscopes don't see much smaller than a nucleus very well, organelles such as mitochondria are seen as specks if you have a good microscope. To see more detail, you need an electron microscope (transmission or scanning), with which you can even see objects as small as viruses.
To see particles, such as individual cells or microorganisms, you would typically need a light microscope. However, to see smaller particles like viruses or nanoparticles, you would need an electron microscope.

You would need a scanning electron microscope (SEM)
