well I don't know about single organisms but single celled organisms are of coarse organisms with only one cell
yes bacteria is a single celled organisms.
what is the group of mainly single celled organisms called
Amoebas are single celled organisms. They do not have any particular shape. Another group of single-celled organisms like amoebas are protists.
Yes, all organisms begin as a single-celled zygote. Then they undergo meiosis and mitosis to replicate if they are multicellular or stay the same if they are single celled organisms.
Usually Bacteria is unicellular, but in some cases multicellular.
Unicellular organisms are complete living entities consisting of a single cell that carries out all life processes, while a single cell is the basic structural and functional unit of living organisms. Essentially, all unicellular organisms are single cells, but not all single cells are complete unicellular organisms.
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).
no
yes bacteria is a single celled organisms.
Sinle celled organisms are called "microorganisms". Bacteria are microorganisms with no nucleus. Protists are single celled organisms that are like animals because they have a nucleus. Examples: amoeba, paramecium
No they aren't
