To solve this question, we need to identify the domains that contain only one type of body structure. Let's review the table provided and analyze the information for each domain and kingdom step by step:
1. Bacteria
- Kingdom: Eubacteria
- Body type: Unicellular
- Cell type: Prokaryote
2. Archaea
- Kingdom: Archaebacteria
- Body type: Unicellular
- Cell type: Prokaryote
3. Eukarya
- Kingdoms under Eukarya:
- Protista: Most are unicellular
- Fungi: Both unicellular and multicellular
- Plantae: Multicellular
- Animalia: Multicellular
Now, let's interpret the question and find out which domains contain only one body type.
- The domain Bacteria contains kingdoms with organisms that are all unicellular (one body type).
- The domain Archaea also contains kingdoms with organisms that are all unicellular (one body type).
- The domain Eukarya has kingdoms with both unicellular and multicellular organisms, hence it does not have only one body type.
- When we look at the individual kingdoms, even within Eukarya itself:
- Fungi has both unicellular and multicellular organisms.
- Plantae and Animalia are entirely multicellular but these are under Eukarya which doesn't fit our requirement directly.
From the analysis:
- Possible Choices:
- Fungi and Eukarya: Doesn't fit, as Eukarya does not have only one body type.
- Bacteria and Archaea: Both domains have only one body type (unicellular).
- Eukarya and Fungi: As explained, Eukarya has multiple body types, and so does Fungi.
- Plantae and Bacteria: Plantae belongs to Eukarya which has both unicellular and multicellular types.
Hence, the correct answer is:
- Bacteria and Archaea
Therefore, based on the table, the domains that contain only one body type are Bacteria and Archaea.
