The Three Domains

Archaea is full of microscopic organisms that can survive in the harshest of conditions.
Bacteria consists of microscopic life that can either harm us or help us.
Eukaryota are either uni- or multi- cellular organisms which are generally the most complex.

Kingdoms:
Archaea

• Thermophiles are organisms that survive in extremely hot environments.
• Halophiles can survive in extremely salty environments.

Bacteria

• Cyanobacteria- These bacteria obtain energy through photosynthesis.
• Heterotrophic bacteria- The typical bacterium obtains energy from its environment.

Eukaryota

• Fungae- They are similar to plants, however, they are heterotrophic and their cell walls contain chintin.
• Animalia- This kingdom contains complex, multicellular organisms that do not use chlorophyl.
• Plante- These multicellular organisms generally use photosynthesis for energy and stay rooted in one spot.
• Protista- These are (typically) unicellular eukaryotes. Some live in colonies, like bacteria. They are typically
