Single-celled organisms are capable of carrying out all necessary functions for survival within one cell due to their simple structure. Each cell performs all functions such as obtaining nutrients, reproducing, and eliminating waste, making multiple cells unnecessary. This simplicity allows single-celled organisms to efficiently carry out their life processes.

What is a singel celled organisms?

There are many single celled organisms (unicellular).Life on Earth is separated into two main divisions: the prokaryotes and the eukaryotes. Both of these contain single celled organism.The prokaryotes are the eubateria and the archaebacteria. Both of these kingdoms only contain single celled organisms. Prokaryotic organisms have no nucleus and have no membrane bound organelles.Within the eukaryotes the kingdoms of amoebozoa, fungi and plantae contain single celled organisms. In all cases these organisms have a nucleus and membrane bound organelles.The amoebozoa kingdom contains such things as the amoeba and slime molds. Fungi comprise the molds, mushrooms, toadstools and other similar organisms. Plantae are the plants.
