Which kingdom is composed of eukaryotes that are multicellular, photosynthetic autotrophs with a cell wall containing cellulose?

• A. Fungi
• B. Protista
• C. Plantae
• D. Animalia

Answer: (C)

The main idea is that plants are eukaryotic, multicellular organisms that perform photosynthesis and have cellulose in their cell walls. This combination of features is what defines the Plantae in this context. Plants use chloroplasts to capture light energy and build sugars (autotrophy), their bodies are composed of many cells with organized tissues, and their cell walls are made of cellulose. Fungi, in contrast, are heterotrophs with chitin in their walls; animals lack cell walls; and protists are a diverse group that includes many unicellular or simple multicellular organisms and do not share the same uniform set of features as plants. So, the group that fits all the described traits is the one comprising plants.
