Over a span of a couple of weeks, we learned and researched a lot about marine microorganisms and algae. We had to research descriptions of many different types of microbes, we also had to draw the different types. You can find the descriptions of all the microbes I have researched.
Diatoms eukaryotic, unicellular, some fore chains, they are mostly planktonic, important primary producers, include frustules made of siliceous sediments.
Cyanobacteria prokaryotic, photosynthesizes for food and energy.
Radiolarian eukaryotic, unicellular, some are colonial, mostly plantonic, heterotrophs, shells are components of siliceous sediments.
Bacteria prokaryotic, unicellular, some form colonies, essential role in nutrient cycles, autotrophs and heterotrophs, including decomposers, nitrogen fixers, some cause diseases, some produce blooms.
Foraminiferan eukaryotic, unicellular, bottom dwelling and planktonic, heterotrophs, shells are components of calcareous sediments.
Dinoflagellates eukaryotic, unicellar, two flagella, mostly planktonic, some bottom dwelling, primary producers, symbiotic with other organisms such as zooxanthellae, red tides, many are bioluminescent, some cause diseases.
Phaeophyta brown algae pigment is fucoxanthin, abundant in cold water, inhabit intertidal zones.
Rhodophyta red algae pigment is phycobilins, has a simplified structure, some are parasites of other seaweed.
Chlorophyta green algae pigment is chlorophyll, multicellular, inhabit mostly terrestrial and freshwater, simple thallus, common on rocks and tidepools.
