Yes. They are referred to as single-celled organisms. Some examples are bacteria and many other prokaryotes. blaine allen reeder was here.
organisms cannot exist in a single cell. organisms can be single- celled, then they are called unicellular orgnaisms.
An eukaryotic cell just means that it has membrane bound organelles and a nucleus. single cell organisms are organisms that are solo, they aren't cell specialized. Single cell organisms can be eukaryoic or prokaryotic (no membrane bound organelles and no nucleus) cells.
....as opposed to? Having no cells? All living things must be composed of at least one cell.
In multicellular organisms, cell might have seperate jobs or tasks.In a unicellular organisms,the only cell present will have to complete all tasks necessary for survival.With multicelled organisms ,it allows for certain cells to specialize in their function and divide the labour between multiple different cell groups.
Multicellular organisms, of course! Unicellular organisms have one cell, so no cellular specialization.

They are not all many celled. Yeast is a fungs and is composed of just one cell.

Unicellular organisms
There are many ways that viruses are NOT like living organisms. Viruses differ from living organisms in the following ways: • Viruses cannot reproduce without the help of a host cell • Viruses do not metabolize organic nutrients, but instead use ATP made by the host cell. • Viruses are not separated from their external environment by some sort of barrier like a cell wall or membrane. • Viruses contain either DNA or RNA but never both. A virus can also be like organisms in that they still consist of macromolecules like proteins, nucleic acids, carbohydrates and lipids just like organisms do.

Just Because it's so small does not mean it isn't an organism. == Answer== Some organisms are unicellular, meaning that are composed of only one cell. Life started as unicellular organisms which turned more complex later.

cell classification can be use full for ideynifing organisms if you know what kind of cell the organism has and can identify it to a cell just like it.
One way that single-celled organisms are different from multi-celled organisms is in their complexity. Single-celled organisms consist of just one cell, while multi-celled organisms are made up of multiple cells organized into specialized tissues, organs, and systems. This allows multi-celled organisms to perform more complex functions and have greater structural and functional diversity.
Unicellular organisms and gametes
A cell is the smallest part of a living organism that contains the identity within a strand of DNA. The cells of your body can grow into specialized functions such as heart or skin. Some microscopic organisms are 1 cell creatures or simple multi-cell organisms. That is what is mean by "All living organism are composed of cells."
I suppose it's really just called DNA, but in some singe-celled organisms, it's just simply DNA. The DNA is found in the nucleus of a cell.
