Bacteria
The cell kingdom that includes both multicellular and unicellular organisms is the Protista kingdom. This kingdom consists of various types of eukaryotic organisms that do not fit into the other major kingdoms (Animalia, Plantae, Fungi). Some protists are unicellular, while others are multicellular.
Fungi and Protista.
The organism belongs to the Kingdom Protista. This kingdom includes eukaryotic organisms that are unicellular or multicellular but lack specialized tissues, such as protozoa and algae.
The kingdom in the Eukarya domain that includes unicellular autotrophs is the Kingdom Protista. This diverse group of organisms includes algae, which are able to produce their own food through photosynthesis. Algae can be found in various aquatic environments, from freshwater to marine habitats.
Unicellular.
The kingdom that includes bacteria is the Kingdom Monera. This kingdom is made up of unicellular prokaryotic organisms that lack a distinct nucleus and membrane-bound organelles. Bacteria are considered to be one of the major groups within this kingdom.
It contains both. Kingdom Protista is a large and very diverse group of organisms and can live as unicellular, multicellular, and in some cases, colonial cells.
Bacteria
The kingdom of protists has both heterotrophs, autotrophs, and uni/multicellular organisms.
The kingdom Protista consists primarily of unicellular eukaryotic organisms. This diverse group includes protozoans, algae, and slime molds, which possess a variety of different characteristics and lifestyles.
The Whittaker version of Kingdom Plantae is all multicellular. However, Plantae has been recently changed to Viridiplantae and now includes the green algae, which contain many unicellular forms.
It includes mostly unicellular organisms that do not fit into the other kingdoms.
