The Six Kingdoms

Before we get to the kingdoms… Prokaryote: An organism whose cells lack a nucleus some other cell structures. Eukaryote: An organism with cells that contain nuclei and other cell structures. Heterotroph: An organism that cannot make its own food. Autotroph: An organism that can make its own food.

This is how scientists classify today: Is it unicellular or multicellular? Is it a heterotroph or an autotroph? Is it a prokaryote or a eukaryote? 1 cell More than 1 cell Can’t make its own food Makes its own food Lacks a nucleus Has a nucleus

Archaebacteria “Ancient Bacteria”. Already existed on Earth for millions of years before dinosaurs appeared. Examples: bacteria that live in extremely hot environments. Classification: Unicellular Autotrophs or heterotrophs Prokaryotes

Eubacteria Bacteria that produce yogurt. Bacteria that give you strep throat. Classification: Unicellular Autotrophs and Heterotrophs Prokaryotes

Protists “odds and ends” kingdom. Examples: Seaweed, algae, amoeba, paramecium, euglena. Classification: Most are unicellular Autotrophs and Heterotrophs Eukaryotes

Fungi Mushrooms, Mold, and Mildew. Feed on dead or decaying organisms. Classification: Multicellular (except yeast) Heterotrophs Eukaryotes

Plants Without plants life on Earth would not exist. Why? Plants feed almost all heterotrophs on Earth. Dandelions in a field, mosses in a forest, and tomatoes in a garden. Classification: Multicellular Heterotrophs Eukaryotes

Animals Animals have different adaptations that allow them to locate food, capture it, eat it, and digest it. Classification: Multicellular Heterotrophs Eukaryotes
