1. List in order taxonomic categories used in organisms.
Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species
2. Distinguishing characteristics of taxonomic groups
Domain Archaea - Archaea thrive in extreme environments and are prokaryotic cells. The have unusual proteins and other molecular adaptations. Extreme halophiles live in salty environments. Thermophiles thrive in environments with high temperatures. Methanogens live in oxygen-lacking environments and produce methane which can be found in marshes, animals and humans.
Domain Bacteria- Bacteria has organisms that are similar with each other and can live anywhere. They are also prokaryotic cells. Most bacteria are decomposers and few can cause disease. AS of late, they have been known to be used as biological weapons. They are divided into five groups based on their genetic sequences.
Domain Eukarya- It includes all of the organisms with eukaryotic cells, some unicellular and some multicellular. They have cell division by mitosis. Domain eukarya is subdivided into four kingdoms: Protista, Fungi, Plantae, and Animalia.
Kingdom Protista- Protista are unicellular, eukaryotic organisms, but some are multicellular. They live in water, some in moist soil or on the human body. They can be heterotrophic and autotrophic.
3. Flagellated protozoans (Phylum Zoomastigophora)- Giardia
Amoeboid protozoans (Phylum Sarcodina) - pseudopodia
Ciliated Protozoans (Phylum Ciliphora)- paramecium
Sporozoans (Phylum Sporozoa) - malaria
Euglenoids (Phylum Euglenophyta)- mixotrophs
Dinoflgellates (Phylum Dinoflagellata)
Diatoms (Phylum Bacillariophyta)- plankton
Phylum Acrasiomycota-cellular slime molds
Phylum Myxmomycota- plasmodial slime molds
4. The patterns of reproduction in prokaryotes and protists
Prokaryotes reproduce quickly in a favorable environment. They rapidly reproduce a new generation within hours and reproduce by binary fission.
