Answer :
To determine which domains contain only one body type, we need to examine the characteristics provided in the table for each domain.
1. Bacteria:
- Kingdom: Eubacteria
- Body type: Unicellular
- Cell type: Prokaryote
In the Bacteria domain, the kingdom Eubacteria consists of organisms that are unicellular only.
2. Archaea:
- Kingdom: Archaebacteria
- Body type: Unicellular
- Cell type: Prokaryote
In the Archaea domain, the kingdom Archaebacteria consists of organisms that are unicellular only.
3. Eukarya:
- Kingdom: Protista
- Body type: Most unicellular
- Cell type: Eukaryote
- Kingdom: Fungi
- Body type: Both unicellular and multicellular
- Cell type: Eukaryote
- Kingdom: Plantae
- Body type: Multicellular
- Cell type: Eukaryote
- Kingdom: Animalia
- Body type: Multicellular
- Cell type: Eukaryote
In the Eukarya domain, the organisms show a variety of body types: unicellular in Protista, both unicellular and multicellular in Fungi, and multicellular in Plantae and Animalia.
Considering this information:
- The Bacteria domain contains only unicellular organisms.
- The Archaea domain also contains only unicellular organisms.
- The Eukarya domain contains both unicellular and multicellular organisms.
Thus, the domains containing only one body type, which is unicellular, are Bacteria and Archaea.
The correct answer is:
Bacteria and Archaea.
1. Bacteria:
- Kingdom: Eubacteria
- Body type: Unicellular
- Cell type: Prokaryote
In the Bacteria domain, the kingdom Eubacteria consists of organisms that are unicellular only.
2. Archaea:
- Kingdom: Archaebacteria
- Body type: Unicellular
- Cell type: Prokaryote
In the Archaea domain, the kingdom Archaebacteria consists of organisms that are unicellular only.
3. Eukarya:
- Kingdom: Protista
- Body type: Most unicellular
- Cell type: Eukaryote
- Kingdom: Fungi
- Body type: Both unicellular and multicellular
- Cell type: Eukaryote
- Kingdom: Plantae
- Body type: Multicellular
- Cell type: Eukaryote
- Kingdom: Animalia
- Body type: Multicellular
- Cell type: Eukaryote
In the Eukarya domain, the organisms show a variety of body types: unicellular in Protista, both unicellular and multicellular in Fungi, and multicellular in Plantae and Animalia.
Considering this information:
- The Bacteria domain contains only unicellular organisms.
- The Archaea domain also contains only unicellular organisms.
- The Eukarya domain contains both unicellular and multicellular organisms.
Thus, the domains containing only one body type, which is unicellular, are Bacteria and Archaea.
The correct answer is:
Bacteria and Archaea.
