Term	Definition
Virus	A protein and its DNA - not alive per se in they cannot metobolize on their own
Archaea	Virus Domain - oldest inhabitants of earth - prokaryotes - all life has evolved from these organisms
Eubacteria	Virus Domain - more evolved than archaea - prokaryotes - typically referred to as bacteria
Eukaryota	Virus Domain - made up of eurkaryotes
Monera	1st Kindom - Prokaryotic organisms lacking membrane bound organelles. Bacteria fall into this kingdom
Protista	2nd Kingdom - Simple eukaryotic organisms not complex enough to fall into the next kingdoms - reproduce sexually & may display mobility using flagella - algea & some water molds
Fungi	3rd Kingdom - Eukaryotic organisms with multinucleated cells - decompose dead & dying organisms to obtain energy - cannot produce own food - mushrooms, molds, & yeast
Plantae	4th Kingdom - Multicellular eukaryotes possessing cell wall, lack mobility & produce food thru photosynthesis - reproduce sexually - mosses, flowering plants, grasses
Animalia	5th Kingdom - Multicellular eukaryotes not possessing cell walls & are mobile during some part of their lifespan - cannot self-reproduce, reproduce sexually - cats, dogs, humans, fish
Archeabacteria	Most primative (& rare) life form - exist in anaerobic environments - can use sulfur in place of oxygen to produce ATP
Eubacteria	True bacteria - found thru-out planet - microscopic - come in rod-like, spherical, or long twisted shapes
Autotrophic Eubacteria	Produce their own food via photosynthesis
Heterophic Eubacteria	Get their food from other organisms (E. coli)
Protista	Oldest Eukaryotes - single-celled or multi-cellular organisms with a nuclear membrane - may be independent or live in colonies
Animal-like Protista	Single-celled heterotrophs - protozoans (amoebas & parameciums) - can be parasitic & be a source of human disease (malaria)
Plant-like Protista	Autotophic - can be colonial, forming elaborate algea, or can exist individually - diatoms & dinoflagellates
Fungi-like Protista	Exhibit fungi behaviors - slime mold
Saprotrophic Fungi	Obtain food by ingesting dead organisms
Oomycota Saprotrophic Fungi	Reproduce sexually - water molds - causal agent for many agricultural catastrophes (Irish Potato Famine)
Zygomycota Saprotrophic Fungi	Reproduce asexually or sexually - bread mold
Ascomycoata Fungi	Largest division - form lichens thru symbiosis with algae - may reproduce sexually or asexually - saprotrophic
Basidiomycota Fungi	Reproduce sexually via their fruiting bodies - mushrooms, puffballs, shelf fungi..
Deuteromycota Fungi	Very little is known about this group - causal agents for athlete's foot & ringworm
Mycorrhizae	Structures created by a symbiotic relationship of certain fungi with plant roots
Rhodophytes	Aquatic plant - red algea - live in water - oldest & most primative plants - cannot transport nutrients & water therefore unable to grow very large
Phaeophytes	Aquatic plants - brown algae - exhibit a pronounced alternation of generations
Chlorophytes	Aquatic plants - green algea - ancestors of terrestrial plants - store carbohydrates as starch, have cell walls made up of cellulose, have chlorophyll pigments - nonvascular - mainly freshwater plants
Bryophetes	Nonvascular terrestrial plants - mosses - demonstrate a distinct alternation of generations where gametophytes are the dominant form.
Rhizoids	Analagous to a root - anchor Bryophetes to the ground but do not conduct water transport
Pterophytes	Vascular Terrestrial Plants - Ferns - dominant generation is sporophyte - 1st with leaves, roots, & organs for transporting nutrients & water
Gymnosperms	Vascular Terrestrial Plants - Conifers (evergreens) - naked seeds - don't form flowers
Angiosperms	Vascular Terrestrial Plants - Flowering plants & deciduous trees - most evolved & successful group of plants
Porifera	Animal phylum - sponges - reproduce sexually & asexually - lack even a rudimentary nervous system
Cnidaria	Animal phylum - jellyfish, coral - exhibit radial symmetry & possess rudimentary nervous sytem - reproduce sexually & asexually
Platyhelminthes	Animal phylum - flatworms - more advanced nervous system with nerves & nerve clusters - 1st group with bilateral symmetry - digestive system consists of a gut with one opening
Nematoda	Animal phylum - roundworms - possess a more advanced nervous & digestive system - reproduce sexually
Mollusca	Animal phylum - clams, mussels - much more advanced nervous system with a rudimentary brain - exhibit 1st semblance of a distinct circulatory system & digestive tract w/two openings - reproduce sexually
Annelida	Animal phylum - earthworms - 1st group to demonstrate segmentation - a closed circulatory system - blood is separate from other fluids - each segment has a pseudo brain
Arthropda	Animal phylum - lobsters, spiders - hard exoskeleton & jointed limbs - brain & nervous cord - largest number of animals of any phylum
Echinodermata	Animal phylum - sea stars, sand dollars - deuterostomes (1st opening in digestive system became anus, 2nd the mouth)
Deuterostome	The first opening in the development of the digestive system became the anus, the second became the mouth
Protostomes	The first opening in the development of the digestive system became the mouth
Hemichordates	Animal phylum - marine worms - intermediate between enchinoderms & chordates
Chordata	Animal phylum - fish, birds, mammals - common characteristics include: notochord, dorsal hollow nervous cord, gill slits, bilateral symmetry, 3 embryonic germ layers, and coleom
Notochord	Rigid, cellular rod covered with supporting fibers - backbone
Dorsal Hollow Nervous Cord	Spinal cord - important in cellular communication
Coleom	Cavity between the gut and the body wall
Taxonomy	Identification & classification of organisms: Kingdom - Phylum - Class - Order - Family - Genus - Species
Binomial Nomenclature	Identifying species with only two words - 1st = genus, 2nd = species
