Additional Information:

• 2 kingdom classification given by Linnaeus.
• 5 kingdom classification given by R.H. Whittaker.
• 5 kingdom classification includes: Monera, Protista, Fungi, Plantae, Animalia.

1. Monera: Prokaryotic unicellular (lacks nucleus; nuclear membrane contains genetic material but free in cytoplasm), CHEMOSYNTHETIC AUTOTROPHS/HETEROTROPHS
2. Protista: Unicellular eukaryots (well defined nuclear membrane), AUTOTROPHS/HETEROTROPHS
3. Fungi: Multicellular eukaryote, cell wall made up of chitin, HETEROTROPHIC ABSORPTION/SEPAROPHYTE (depend upon dead material)
4. Plantae: Multicellular eukaryote, AUTOTROPHS.
5. Animalia: Multicellular eukaryote, HETEROTROPHS
