Study Notes
Domain Classification
- Archaebacteria and Eubacteria belong to different domains
- Protista, Fungi, Plantae, and Animalia belong to the Eukarya domain
Characteristics of Each Domain
Fungi
- Most are unicellular, some are multicellular, and a few are colonial
- Cell walls are composed of chitin
- Decomposers and heterotrophs
- Examples: mushrooms, yeast, mold
Plantae
- All are multicellular
- Cell walls are composed of cellulose
- Autotrophs, produce their own food
- Examples: mosses, ferns, cycads, ginkgos, conifers, and flowering plants
Animalia
- All are multicellular
- No cell walls
- Heterotrophs, do not produce their own food
- Examples: sponges, worms, mammals, fish, insects, etc.
Protista
- Unicellular, multicellular, and colonial forms exist
- Cell walls may be present or absent
- Autotrophs and heterotrophs
- Examples: amoeba, kelp, algae
