Marine Life Phytoplankton

Six Kingdoms Archaebacteria—blue green algae or cyanobacteria Eubacteria—true bacteria Protista Fungi Plants Animalia

Kingdom Phylum-----divisions Class Order Family Genus Species

Bacteria Heterotrophic—most are decomposers Autotrophic---photosynthetic or chemosynthetic No organelles Represent the smallest living organisms on earth Reproduce rapidly (about twice an hour)

Prokaryotic producers Cyanobacteria---blue green algae Can tolerate a huge change in salinity and temperature Some of these are nitrogen fixers

Protists Three types Plant like Animal like Fungus like

Plant like Diatoms Dinoflagellates Silicoflagellates There are more but we discuss these

Diatoms Eukaryotic Photosynthesize Reproduce sexually or asexual 12,000 species They have silica shells called frustules Called golden brown algae from the pigment carotenoid

Diatom reproduction Sexual asexual

dinoflegellates They have flagella They spin Unicellular They have a primitive eyespot—sense light They can be seen in the light Cause algal blooms—red tide

Red tides

bioluminescence Produce light--

silicoflagellates Star shaped Have silica in their cell walls flagella

protozoans Animal like protists Euglena Amoeba paramecium

foraminiferans Phylum forminfera Mostly marine Shells of calcium carbonate Psuedopods can retract

foraminiferans Phylum radiolarians Round elaborate shells Made of silica Rotating spines

foraminiferans Phylum ciliophora
