To determine which kingdom the described organism falls into, we need to analyze the provided characteristics.
- Eukaryotic: This means the organism has complex cells with a nucleus.
- Multicellular: The organism is made up of multiple cells.
- Lacks a cell wall: Unlike plant cells, which have a cell wall made of cellulose, or fungi, which have a chitin-based cell wall, this organism does not possess a cell wall.
Given these characteristics, we can evaluate the options:
- Protista: This kingdom includes both unicellular and multicellular organisms. However, many protists, particularly algae, often have cell walls.
- Fungi: Fungi are primarily multicellular and have a cell wall made of chitin, so they do not fit the description.
- Animalia: This kingdom consists of multicellular, eukaryotic organisms that lack a cell wall, which matches our organism perfectly.
- Archaebacteria: This kingdom includes prokaryotic organisms, so it’s not applicable here.
- Eubacteria: Like archaebacteria, this kingdom also consists of prokaryotic organisms and does not fit the criteria.
Based on the characteristics given, the correct classification for the organism in question is c. Animalia.
