It is called an unicellular microorganism. Protoctist are examples.
It means A tiny living thing.
Crystals (and possibly the National Debt)
A virus is not similar to a cell, although it requires a host cell to reproduce. The only thing in common that a virus has to a cell is it has DNA.
A Cell Wall is the outer non-living layer only found in plant cells. It is flexiable to let thing in and out.
The answer to this question varies. One thing that is interesting is that bacteria has different shapes. They also are living and have only one cell.
Unicelluar animals like bacteria
Unicellular
The term is unicellular or acellular
It means A tiny living thing.
If a living organism is only one cell, then it is unicellular. Any singular bacterium serves as an example.
The cell is the living thing - and according to the cell theory it is the smallest unit of life... therefore the things inside a cell are not considered living by themselves, but only all together as a cell.
Bacteria cells are smaller than animal cells. While a bacteria cell is about one micron, an animal cell is about 10 microns. From this data, about ten bacteria cells will fit into an animal cell.
An organism that only exist as a group of cell is called multicellular organism. It is a living thing that is made of more than one cell.
They are considered living organisms. But what about the skin cells which are non-living cells. They are replaced by new cells every day. Another similar aspect of a cell being non-living to this respective question is that the cork discovered by Robert hook cointained ceels then only he was able to define the term cell cork is non-living cell.
