-Plants (Photosynthesis)
-Animals (Ingestion)
What are the 5 kingdoms?
Monera - unicellular, prokaryotic
Protista - Unicellular and simple, eukaryotic
Animalia - Eukaryotic, multicellular, heterotrophic
Plantae - Eukaryotic, multicellular, and photosynthetic
Fungi - Eukaryotic, unicellular and multicellular, and decomposers.
What are living things grouped according to?
Characteristics
What is the new three-domain classification system?
The three domains are:
Eubacteria
Kingdom:
-Bacteria
Eukaryota
Kingdom:
-Animalia
-Plantae
-Fungi
-Protista
Archaea
Kingdom:
-Archaea
