Kingdom Fungi:
- Cell Structure: Eukaryotic; typically have chitinous cell walls.
- Mode of Nutrition: Heterotrophic; absorb nutrients from their surroundings via hyphae (thread-like filaments). They are saprophytic (decomposers) or parasitic.
- Level of Organisation: Mostly multicellular, with some unicellular forms (yeasts). Hyphae form a mycelium.
Kingdom Plantae:
- Cell Structure: Eukaryotic; have cellulose cell walls; contain chloroplasts for photosynthesis.
- Mode of Nutrition: Autotrophic; produce their own food through photosynthesis.
- Level of Organisation: Multicellular; organized into tissues, organs, and organ systems.
Kingdom Animalia:
- Cell Structure: Eukaryotic; lack cell walls.
- Mode of Nutrition: Heterotrophic; ingest food. Diverse feeding strategies (herbivores, carnivores, omnivores).
- Level of Organisation: Multicellular; organized into tissues, organs, and organ systems. Most are capable of movement.
Comparison Table:
| Cell | Nutrition | Organisation |
| Eukaryotic, often with cell walls (fungi) | Fungi: Absorptive (saprophytic/parasitic). Plants: Autotrophic (photosynthesis). Animals: Ingestive. | Fungi: Mostly multicellular. Plants: Multicellular (tissues, organs). Animals: Multicellular (tissues, organs, systems). |
