some of the difrrences is the size shape and the way they work
Usually Bacteria is unicellular, but in some cases multicellular.
yes bacteria is a single celled organisms.
single celled organisms
what is the group of mainly single celled organisms called
well i know that multi cellular organisms have a much more complecated structure and process but a single cellular organism has a process called the cellular resportary syestem and this works well but mostly on small single celled organisms becasue if you had a large organisms the size or dogs then by the time the oxygen from the H2O would get to the nuclei the paramecium or what ever organism you are specifying it would die that is why single celled organisms are so small...size matters
Amoebas are single celled organisms. They do not have any particular shape. Another group of single-celled organisms like amoebas are protists.
Bacteria are single-celled organisms.
There are more single-celled organisms on Earth than multi-celled organisms. Single-celled organisms, such as bacteria and protists, are abundant and diverse, occupying various environments. Multi-celled organisms, including plants, animals, and fungi, represent a smaller proportion of Earth's biodiversity.
"unicellular"
Single-Celled Organisms (Kid's Guide to the Classification of Living Things) was written by Elaine Pasco.
The kingdom Protista contain all single celled organisms. Examples are: protozoans (animal-like single celled organisms) and algae (plant-like single celled organisms).
Prokaryotes are single-celled organisms without a nucleus or membrane-bound organelles, while eukaryotes are more complex organisms with a nucleus and membrane-bound organelles. Eukaryotes can be single-celled or multicellular, while prokaryotes are always single-celled.
