Transcript text: A teacher says she has identified an organism with these characteristics: eukaryotic, multicellular, autotrophic, and a cell wall made of cellulose. Which kingdom is the teacher describing?
Animalia
Protista
Plantae
Eubacteria
Solution
The answer is the third one (C): Plantae.
Explanation for each option:
Animalia: Organisms in the Animalia kingdom are eukaryotic and multicellular, but they are heterotrophic (not autotrophic) and do not have cell walls made of cellulose. Therefore, this option is incorrect.
Protista: This kingdom includes a diverse group of organisms, some of which can be autotrophic and have cell walls. However, they are often unicellular or simple multicellular organisms, and their cell walls, if present, are not typically made of cellulose. This option is less likely to fit all the given characteristics.
Plantae: Organisms in the Plantae kingdom are eukaryotic, multicellular, and autotrophic, with cell walls made of cellulose. These characteristics match the description provided by the teacher, making this the correct option.
Eubacteria: These are prokaryotic organisms, which means they do not have a true nucleus, and they are not typically multicellular. Their cell walls are made of peptidoglycan, not cellulose. Therefore, this option is incorrect.
In summary, the organism described by the teacher fits the characteristics of the Plantae kingdom.
