Term
Crytophytes
Definition
Eukaryotic, unicellular, usually two flagella, planktonic, variety of types of major food reserves, cell membrane made up mostly of protein, important primary producers
Term
Ciliates
Definition
Eukaryotic, unicellular, planktonic and bottom-dwelling; heterotrophs, some associated with marine animals
Term
Archaea
Definition
Prokaryotic, unicellular; autotrophs and heterotrophs, nitrogen fixers; pigments, Bacteriorhodopsin in light-capturing Archaea
Term
Silicoflagellates
Definition
Eukaryotic, unicellular, two flagella, planktonic; primary producers, skeletons are components of siliceous sediments, some produce blooms;pigments, chlorophyll a, c, fucoxanthin
Term
Dinoflagellates
Definition
Eukaryotic, unicellular, two flagella, mostly planktonic, some bottom-dwelling; primary producers, symbiotic with other organisms as red tides, many are bioluminescent, some cause diseases
Term
Fungi
Definition
Eukaryotic, unicellular or multicellular, mostly bottom-dwelling; decomposers, many cause diseases, symbiotic with algae or cyanobacteria in lichens
Term
Bacteria
Definition
Prokaryotic, unicelluar, some form colonies; essiental role in nutrient cycles, autrotrophs and heterotrophs, nitrogen fixers; components of detritus, some cause diseases, symbotic in many organisms;pigments=chlorophyll a, phycobilins, carotenoids in cyanobacteria
Term
Foraminiferans
Definition
Unicellular, bottom-dwelling and planktonic; heterotrophs, shells are components of calcareous sediments
Term
Radiolarians
Definition
Eukaryotic, unicellular, some colonial, mostly planktonic; heterotrophs, shell are components of siliceous sediments
Term
Coccolithophorids
Definition
Eukaryotic, unicellular, one or two flagella, planktonic; important primary producers, plates are components of calcareous sediments, some produce blooms; pigments:chlorophyll a, c, carotenoids
Term
Viruses
Definition
non-cellular parasites of all organisms; capsis of protein, sometimes lipids; releases dissolved organic matter (DOM) from destroyed cells
Term
Diatoms
Definition
Eukaryotic, unicellular, some form chains, mostly planktonic; important primary producers, frustules are components of siliceous sediments; pigments=chlorophyll  carotinoids
