For each of the following, read the characteristics and then identify the kingdom. is mostly unicellular, eukaryotic, and is comprised of eukaryotes that do not fit into other eukaryotic kingdoms. is unicellular, prokaryotic, and has a cell wall that contain peptidoglycan. is unicellular, prokaryotic, has a cell wall, and often lives in extreme environments.

1. Kingdom Protista

2. Kingdom Eubacteria

3. Kingdom Archaeabacteria

Explanation:

1. Kingdom Protista is one of the the six kingdoms. It consists of organisms called PROTISTS that are eukaryotic i.e. possess a membrane-bound nucleus and mostly single-celled (unicellular). Protists are eukaryotic organisms like plants, animals and fungi but their characteristics do not fit into any of these three eukaryptic groups. Protists include; algae, amoeba, etc.

2. Kingdom Eubacteria, as their name implies, are known as true bacteria. The constituent organisms of this kingdom are prokaryotic i.e. lack a membrane-bound nucleus and single-celled (unicellular). They possess a cell wall, in addition to their cell membrane, that is made up of PEPTIDOGLYCAN. Examples of organisms in this kingdom are Streptococcus, Bacillus etc.

3. Kingdom Archaebacteria were once grouped together with the true bacteria as kingdom Monera but were split because of their obvious differing characteristics. Archeans are single-celled prokaryotic organisms characterized majorly by their ability to live and thrive in extreme environmental conditions e.g hot conditions, anoxia conditions (no oxygen).
