One theory is that amoebas are really, really tiny, and that the human eye is unable to magnify the recieved images to see them.
Other theories state that amoebas don't exist, are invivisible and have poor comunication skills.
The Pelomyxa palustris amoeba can be as large as 5mm and can be seen with the naked eye though most can only be seen with a microscope.
No, an amoeba can't see, but it uses other sensory receptors, such as cilia and heat sensing in order to find food and/or hosts.
The largest amoeba can be seen through our naked eye as it can grew as large as 5mm.
Electromagnetic radiation having a wavelengths between 380 - 750nm is visible to the normal human eye. This region of the spectrum is called visible light. Radiation of any other wavelength cannot be seen with the naked eye
microscope
It enables you to zoom in on things that you cannot see with the naked eye
Something that is visible to the naked eye, really!
Magnification is important in science because it allows for the direct observation of processes that are invisible to the naked eye.

Amoebas are unicellular organisms. That is, they are made of one single cell, and are invisible to the naked eye, without a microscope.
They are too small for the naked eye to see.
Some amoebas such as the Pelomyxa palustris are large enough to be seen with the naked eye. Most amoebas would need to be seen under a microscope with at least 400x magnification. Filters are used as white light makes the amoebas curl into a ball and become unrecognisable.
yes but we should have a sharped eye a common person people cant see this
No, the human cannot see ultraviolet rays with the naked eye.
"microscopic" Naked = The average human eye, without the use of any artificial aids like, glasses, microscope, telescope etc.
they allow us to see things that you cant see with the naked eye
No, single-celled organisms can live nearly anywhere. Amoebas can grow to be visible with the naked eye, but are still single celled.

100 um
I'm not sure, but I know that it is the only cell in the human body that can be viewed with the naked eye.
