yes the smallest living orginizms are single celled
the smallest living things are made of of a single cell
This question is vague therefore I have provided two answers and explanations. The single cell is the smallest living unit within a living system. Quarks are the smallest particles of matter and atoms which composes all living things.
eubacteria is the smallest kingdom
The cell is the smallest living thing and an atom is the smallest non-living thing.
The smallest living things depend on how a living thing is defined. Some biologists do not believe viruses are living organisms because there are no free living forms (all are parasitic) and because they must reply on their host for reproduction. Others believe that, despite this, they have an existence of their own separate to the host and are subject to natural selection and are therefore alive. If you accept viruses are not alive, the smallest living things would be amongst the bacteria or protists. Bacteria are single celled organisms with no cell nucleus while protists have a nucleus. Generally the bacteria are slightly smaller but their sizes overlap. If you accept that viruses are alive, the smallest group are the Parvoviruses between 18 and 26 nanometres. These are single stranded DNA viruses. 1 nm = 1/1000000000 metres or 0.000039 inches.
cells
Very tiny living things include microorganisms such as bacteria, viruses, and fungi. These microscopic organisms are essential for various ecological processes and can be found in almost every environment on Earth.
Living Things Are All Made Of Atoms.....It Is The Smallest Part Of Any Element
cells
They are ed
Because a flea is made up of cells, and cells are living things. So the smallest living thing is a cell.
The smallest unit of ecological organization is an individual organism. This could be a single plant or animal that interacts with its living and non-living environment within a specific ecosystem.
