marine bio

phytoplankton

diatoms, dinoflagellates, green algae, cyanobacteria, coccolithophores

plankton

an organism that is carried by tides or currents, cannot swim well enough to move against. usually microscopic but some are large (jellyfish)

Archaeplastida, viridiplantae

green plants, autotrophic chloroplasts from green cyanobacteria, may be uni or multicellular

Archaeplastida, rhodophyta

red algae, possess water soluble pigments that make red, starch not stored in chloroplast but rather in cytoplasm

Coccolithophores

extremely productive and abundant, use up large amount of calcium carbonate. shells formed with coccoliths, abundant in sediments, important food source, produce alkenones that are used to estimate past ocean temps.

coccoliths

overlapping calcium plates

Endosymbiotic Stramenopiles (Sar)

Brown Algae, most paired with flagella, up to 50% oxygen production, 6.7 billion tons of silica for making shells, chloroplasts with fucoxanthin (brown accessory pigment)

Endosymbiotic Alveolata (sAr)

dinoflagellates and all ciliates, have cellulose plates in membrane and paired flagella in groves

Endosymbiotic Rhizaria (saR)

ameboid protists that form elaborate tests (shells), foraminifera multichambered shells made of calcium carbonate, Radiolaria possess needle like axopods and formed silica shells
