350 BC plants/animals

1984; recognized that the plant/animal kingdom division was incomplete, added protists (Protista)

1956; added the Kingdom Monera for bacteria

1959; created 5th Kingdom for Fungi

1977; split bacteria Kingdom into Eubacteria and Archaeabacteria

• eukaryotes that don't fit into any other kingdom
• fit characteristics of life

• size is limited by surface to volume ratio
• no specialization and limited collarboration

brown algea, red algea, green algea

• unicellular (most)
• may form colonial assemblies (many cells with little difference)

an organism permanately associated with other organisms of the same species for a mutal benefit

• have cholorplasts (photosythetic)
• chemosythesis (H2S)
• recyclers
• heterotrophs
• ingesters
• capures the organism

• sexual
• asexual

• flagella
• cilia
• psuedopods
• not mobile

• complex lifecycles both asexual, and sexual
• can have different hosts
• malaria, African sleeping sickness, Giardiasis

• important in food changes
• symbiotes
• parasites
• termites and cellulose
• decomposers
• produced landforms

• Eat decomposing material
• Eukary. multicellular
• cell wall like insects skin
• specialization
• long thin threads for communication between cells
• more like animals that plants
• external digestion
