Unicellular Cells
Cells, Bacteria, and Viruses
Organisms such as bacteria, yeast, algae, fungi, and small protozoa are typically observed with a light microscope due to their size and transparency. These organisms can be magnified to see their cellular structures and characteristics.
Because these organisms are too smaller to be observed directly.
Because, it is too small to see with the naked eye.
yes small is an abstract word because people can see small in different ways you cant see it directly. Even when using your senses
In order to see microshopic(very small) organisms. (like germs.)
Single celled organisms include bacteria, protozoa, yeast, and algae. They are pretty much everywhere on Earth. Most of them are too small to see without magnification (usually by means of a microscope). Some of them cause disease.
A microbiologist would study living organisms that are too small to see with the naked human eye. They study microorganisms such as bacteria, viruses, fungi, and protozoa.
When looking through a keyhole, you typically see a small portion of the room on the other side, usually limited to what is directly in front of the keyhole. The view may be distorted due to the shape of the keyhole and the angle of viewing.
Biology of organisms to small for the human eye to see. This can be anywhere from a single cell, to an organism with a very small number of them.
It is multicellular. Unicellular organisms are too small to see.
Microorganisms are very small and can vary in shape and size. They can be spherical, rod-shaped, spiral, or even branched. To see them, a microscope is usually required as they are too small to be seen with the naked eye.
