Life's Kingdoms

Archaebacteria

Unicellular prokaryotes with a unique lipid composition in their cell walls, lacking peptidoglycan, and can be autotrophic or heterotrophic.

Eubacteria

Unicellular prokaryotes that contain peptidoglycan in their cell walls, functioning as either autotrophic or heterotrophic organisms.

Protista

Mostly unicellular eukaryotes, with varied cell walls, including algae and protozoa, exhibiting autotrophic or heterotrophic nutrition.

Fungi

Mostly multicellular eukaryotes, with cell walls made of chitin, primarily heterotrophic and absorb nutrients from decomposing organic matter.

Plantae

Multicellular eukaryotes with cell walls made of cellulose, autotrophic and capable of photosynthesis using chloroplasts.

Animalia

Multicellular eukaryotes without cell walls, heterotrophic and characterized by the ability to move and possess specialized tissues.
