To classify an organism into Kingdom Animalia, the following characteristics would be relevant:
- Eukaryotic: Animals are eukaryotic organisms, meaning their cells have a nucleus and other membrane-bound organelles.
- Multicellular: Most animals are multicellular, although there are some exceptions in simpler forms.
- Heterotroph: Animals are heterotrophic, meaning they obtain their food by consuming other organisms or organic matter.
- Lack of Cell Wall: Animal cells do not have a cell wall, distinguishing them from plants and fungi.
- Mobile for part of the life cycle: Most animals exhibit some form of mobility at some point in their life cycle.
The characteristics "Prokaryotic," "Unicellular," "Autotroph," "Presence of Cell Wall," and "Sessile" are not used to classify organisms into Kingdom Animalia. Prokaryotic organisms belong to different kingdoms (like Bacteria and Archaea), unicellular organisms do not fit the multicellular requirement, autotrophs are typically found in kingdoms like Plantae, and presence of a cell wall is characteristic of plants and fungi, not animals. "Sessile" can apply to some animals, but animals as a whole are not classified by this trait, as many are mobile.
