Classification Unit 2 ~ The 6 Kingdoms

Archaebacteria

Unicellular organisms that can be autotrophic or heterotrophic, reproduce asexually, and are known as extremophiles with cell walls lacking peptidoglycan.

Eubacteria

Unicellular organisms that can be autotrophic or heterotrophic, reproduce asexually, are common bacteria, and have cell walls containing peptidoglycan.

Protista

Eukaryotic organisms that can be unicellular or multicellular, heterotrophic or autotrophic, reproduce asexually or sexually, and can be plant-like or animal-like.

Fungi

Eukaryotic organisms, mostly multicellular but some unicellular, that are heterotrophs, reproduce sexually or asexually, digest food extracellularly, and have cell walls made of chitin.

Plantae

Eukaryotic, multicellular organisms that are autotrophic (photosynthetic), reproduce asexually or sexually, serve as a food base for communities, and have cell walls made of cellulose.

Animalia

Eukaryotic, multicellular organisms that are heterotrophs, primarily reproduce sexually, move at some stage of life, lack a cell wall, and include species like bears, sharks, insects, and humans.
