Because there is only one cell and they are not as complex as multi celled-organisms. Example: A rabbit needs to perform more functions, while a single celled organism, such as amoeba, doesn't need to perform a lot of functions. The rabbit is more complex, so it has a hierarchy of organization.
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.
Cells in single-celled organisms function independently and carry out all life processes on their own, while cells in multi-celled organisms are specialized to perform specific functions. Multi-celled organisms have different types of cells that work together to support the organism as a whole.
what is the group of mainly single celled organisms called
Eukaryotes can be single-celled or multi-celled and have a defined internal organization with a nucleus and membrane-bound organelles. Prokaryotes are typically single-celled and lack a true nucleus or membrane-bound organelles in their structure.
they are also called unicellular organisms.
Usually Bacteria is unicellular, but in some cases multicellular.
yes bacteria is a single celled organisms.
what is the group of mainly single celled organisms called
Bacteria are single-celled organisms.
Amoebas are single celled organisms. They do not have any particular shape. Another group of single-celled organisms like amoebas are protists.

"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).
no
cause many celled organisms grow faster
All single celled organisms e.g. Bacteria don't use mitosis .
