Chapter 5 Flashcards
Proteins that bind with …….. And good for
Receptors on host cells, mimicry
Many…… Spikes extend from coat so fast that our …. Cannot keep up
Glycoprotein immune system
What is made from lysis
DOM
Largest virus
Diameter: 440 nm in marine amebas
DNA has 1120 genes , more than some bacteria
Characteristics of both bacteria and archaea , nuc?, cell wall
Prokaryotic
Single chromosome
Most cell wall
Great metabolic diversity
Archaeans are normally
Extremophiles
What can archaea tolerate wide ranges of … And where found
Salinity, temp. And desiccation
Hydrothermal vents and salt flats
What size are bacteria normally
Microscopic
Largest bacteria
Thiomargarita
Important job of bacteria
Detritus
Stromalites are a product of what
Bacteria Cyanobacteria build up of calcium carbonate billion years old
How does algae eat
Photosynthesis, single celled animal like traits
What did algae used to be put under
Protista because of animal like traits and lack of plant structures
How do diatoms eat, look like, live together or alone, how many cells , why important ?
Photosynthesis, shell of frustule, unicellular, live alone but can form colonies, important primary producer
Most diatoms are…. Store excess energy as , what toxin do they reproduce, and makes up …. Earth
Planktonic, oil, Domoic acid that accumulates in tissues, diatomaceous earth
Diatoms reproduction
Cellular division, cast off one side of frustule becoming smaller and smaller, cast of frustule and secrete entire new frustule
Dinoflagellates: where do they live, how do they eat, shape reinforced by, flagella?, reproduction…. Special feature
Most in marine, photosynthetic, plates of cellulose, 2 flagella in grooves, cellular division, bioluminescent Bahia fosforescente
Zooxanthellae are what type of organism, they are diff. From typical ones because
Dinoflagellate, non motile no flagella
What organisms make red tides, lack chloroplasts, and are part of pfiesteria
Dinoflagellates, parasitic, serious toxins
Who has blooms which is a result of what, what gets its name from this and are they harmful
Diatoms and dinoflagellates , high levels of nutrients in the water , Red Sea, yes
Unicellular algal plankton
Sillicoflagellates, coccolithophores
Star shaped skeleton of silica, two flagella of diff. Length
Shells of calcium carbonate
What are under Protozoa
Foraminifera so, radiolarians, fungi, Ciliates
Foraminiferans: where do they live, what are they made of, how do they move and eat, what are they contributors of
Exclusively marine, rocky or sandy bottoms, shells of calcium carbonate, pseudopods capture minute food part. Like phytoplankton , calcareous material on coral reefs
What are forums responsible for
Pink beaches
Radiolarians are….. And mostly what size, what are they made of , how do they eat
Planktonic, microscopic, shells of silica, pseudopods like forams
Connected colonies of radiolarians cane reach a. Size of
Meters
Ciliates : move/eat, live as ….., what are they made of, live on,
Cilia, solitary cells, shells of organic debris, hard substrate
Freshwater cilia and planktonic one
Paramecium, tinntinids : vase like Lorica built from sand grains
Fungi: mostly, eat, lack, ,most of 1500 species, were are they important, symbiosis called, where do they live
Multicellular, by breaking down other things heterotroph, microscopic, mangroves, lichens with Cyanobacteria, rocky shorelines or substrate
Cliffs of Dover are made by
Foraminiferans ooze
Which two are prokaryotic
Bacteria and archaea
Viruses are …..cellular …..agents with what two basic characteristics
Non, infectious
Not capable of rep. Without host cell
Nucleic acid core: DNA or RNA
