Because the spectrum of the eye cannot see things smaller them a crumb the size of a grain of dirt. so it can't see a germ
Bacteria, Germs, Microscopic Orginisms - these are all small things, not necessarily invisible!
You have to use a microscope to see 1 microbe but if large amount bacteria grow you can see them quite clearly. They need damp warm environments to grow and there must be a supply of food for them.
its a microbiologist
it helps us look @ small things that the naked eye can't!! :)
because cells are too small to see with the human eye
Bacteria, Germs, Microscopic Orginisms - these are all small things, not necessarily invisible!
No, they are much too small.
Because, it is too small to see with the naked eye.
they are very small in other words Microscopic
Something that is so small that you cannot see it with the naked eye but must use a microscope to observe it

Firstly, the "naked eye" can't detect the wavelength of any kind of electromagnetic radiation outside a very small window of frequencies that correspond to visible light. And secondly, Planck's constant is so small that the de Broglie wavelength of any macroscopic particle is infinitesimal.
No, the human cannot see ultraviolet rays with the naked eye.
because they are too small for the naked eye to see, but there are millions of them all cells die and produce again
Microscopes are used to see small images that are invisible to the naked eye.
MICROBIOLOGY
~100micrometers, depending on how good your eyesight is
