The Six Kingdoms of Life

-Prokaryote -Cell walls without peptidoglycan -Unicellular -Autotroph or heterotroph -Found in extreme environments such as hot sulfur springs and thermal vents under conditions without oxygen or highly acid environments

-Prokaryote -Cell walls with peptidoglycan -Unicellular -Autotroph or heterotroph -Most eubacteria are helpful. Some produce vitamins and foods, like yogurt. However, others like Streptococcus give you strep throat!

-Eukaryotes -Most are unicellular, some multicellular -Some have double shells made of silica -Found in pond water or near water! -Protists are sometimes called the odds and the ends of the kingdoms because its members are so different from one another

-Eukaryote -Cell walls with chitin -Most multicellular, some unicellular -”Absorptive” heterotrophs; get nutrients through extracellular digestion -Fungi are organisms that biologists once confused with plants. Most obtain food from parts of plants that are decaying in the soil

Plantae

-Eukaryotes -No cell walls or chloroplasts -Multicellular -Heterotrophs -Vertebrates & invertebrates -The animal kingdom is the largest of all the six!
