There is no single kingdom that is unicellular. All prokaryotes (organisms with no cell nucleus) are unicellular, and they belong to two domains, bacteria and archaea. Eukaryotes, or organisms with a cell nucleus, are divided into four kingdoms, plants, fungi, animals, and protists (although recently scientists began to reclassify protists into multiple separate kingdoms). In each of the fungi and protist kingdoms, there are a variety of members that are unicellular, and also some members that are multicellular. Animals and plants are always multicellular (except possibly one animal group called Myxozoa).

What is the difference between kingdom monera and kingdom protista?
It includes mostly unicellular organisms that do not fit into the other kingdoms.
Which kingdom contains the smallest organisms?
The kingdom that contains the smallest organisms is the Monera kingdom, which includes bacteria and archaea. These organisms are unicellular and have simple cellular structures compared to other kingdoms.
What kingdom has the least amount of species?
The kingdom with the least amount of species is the kingdom Monera, which consists of unicellular prokaryotic organisms such as bacteria and archaea.
What two domains are composed of only unicellular organisms?
The domains Bacteria and Archaea are composed of only unicellular organisms. These organisms are prokaryotic and lack a true membrane-bound nucleus in their cells.
What are to unicellular phylum of animal kingdom?
The two unicellular phyla in the animal kingdom are Porifera (sponges) and Cnidaria (jellyfish, coral). These organisms consist of individual cells that work together to carry out essential functions, rather than being multicellular like other animals.
