The characteristics that can be true about the plant kingdom are:
- Autotroph: Plants are primarily autotrophic, meaning they produce their own food through photosynthesis.
- Multicellular: Most plants are multicellular organisms.
- Cellulose cell walls: Plant cells have cell walls made of cellulose, which provides structure and support.
The following characteristics are not true for the plant kingdom:
- Chitin cell walls: Chitin is found in the cell walls of fungi, not plants.
- Heterotroph: Plants are not heterotrophs; they do not obtain food from consuming other organisms but rather synthesize their own food.
So the true characteristics about the plant kingdom from your list are: Autotroph, Multicellular, and Cellulose cell walls.
