Question map
Living things are grouped into subgroups like plant kingdom / animal kingdom. Which one of the following is not correct for animal kingdom?
Explanation
The animal kingdom (Animalia) is characterized by multicellular eukaryotic organisms that are heterotrophic, meaning they cannot produce their own food and must consume other organisms [1]. Unlike plants, animals lack chlorophyll and the capacity for photosynthesis [1]. A defining cellular difference is that animal cells do not possess a cell wall. While plant cells have a rigid cell wall composed of cellulose to provide structural support, animal cells lack this feature entirely [3]. Regarding movement, animals generally possess a far greater capacity for mobility and dispersal compared to plants, often exhibiting spontaneous movement and seasonal migration to different habitats. Therefore, the statement that an animal's body contains cellulose is incorrect, as cellulose is a primary component of plant cell walls, not animal tissues.
