Microscopes
One-celled organisms, such as bacteria and protists, generally do not have eyes or the complex sensory organs required for sight. However, they can detect light using photoreceptor proteins that allow them to sense changes in their environment. This helps them move towards or away from light sources in a process called phototaxis.
Yes. One celled or unicellular organisms are so small you would need a strong microscope to see one.
Multi because they are living and breathing. Something like a rock would be single celled.
The microscope
Single-celled organisms are too small to be seen with the naked eye. They lack the complex structures and specialized organs found in multicellular organisms that are visible under a microscope. Additionally, their transparency and lack of pigmentation make them difficult to distinguish without magnification.

No. unicellular organisms only have one cell, so they can only be seen under a microscope.
No, but there are organisms that consists of one cell and those that consists of many cells. Deer, bears, and any other animal you can see, including humans, are multiple celled, and the ones that require an imaging scope are single celled.

There are no single-celled organisms large enough for you to actually see with your naked eye. All animals you can see are multiple cells.
Every organism you can see. Animals,plants are examples
Scientists can see th fossils and the living organisms.
Scientists classify organisms by the dichotomous key. They classify by looking at if it moves or not, then they look at characteristics, then they can see what they are.
No. Single-celled organisms are too small to see without a microscope. An anteater can be mroe than 2 metres head to tail.
A one celled organism is something you see in a microscope like a virus. A bald eagle is a many celled organism.
Multi because they are living and breathing. Something like a rock would be single celled.
A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, in contrast to a multicellular organism that consists of multiple cells.Prokaryotes, most protists, and some kinds of fungi are unicellular.
