Flashcards in Chapter 5 Deck (32):
1

Proteins that bind with ........ And good for

Receptors on host cells, mimicry

2

Many...... Spikes extend from coat so fast that our .... Cannot keep up

Glycoprotein immune system

3

What is made from lysis

DOM

4

Largest virus

Diameter: 440 nm in marine amebas
DNA has 1120 genes , more than some bacteria

5

Characteristics of both bacteria and archaea , nuc?, cell wall

Prokaryotic
Single chromosome
Most cell wall
Great metabolic diversity

6

Archaeans are normally

Extremophiles

7

What can archaea tolerate wide ranges of ... And where found

Salinity, temp. And desiccation
Hydrothermal vents and salt flats

8

What size are bacteria normally

Microscopic

9

Largest bacteria

Thiomargarita

10

Important job of bacteria

Detritus

11

Stromalites are a product of what

Bacteria Cyanobacteria build up of calcium carbonate billion years old

12

How does algae eat

Photosynthesis, single celled animal like traits

13

What did algae used to be put under

Protista because of animal like traits and lack of plant structures

14

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

15

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

16

Diatoms reproduction

Cellular division, cast off one side of frustule becoming smaller and smaller, cast of frustule and secrete entire new frustule

17

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

18

Zooxanthellae are what type of organism, they are diff. From typical ones because

Dinoflagellate, non motile no flagella

19

What organisms make red tides, lack chloroplasts, and are part of pfiesteria

Dinoflagellates, parasitic, serious toxins

20

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

21

Unicellular algal plankton

Sillicoflagellates, coccolithophores
Star shaped skeleton of silica, two flagella of diff. Length
Shells of calcium carbonate

22

What are under Protozoa

Foraminifera so, radiolarians, fungi, Ciliates

23

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

24

What are forums responsible for

Pink beaches

25

Radiolarians are..... And mostly what size, what are they made of , how do they eat

Planktonic, microscopic, shells of silica, pseudopods like forams

26

Connected colonies of radiolarians cane reach a. Size of

Meters

27

Ciliates : move/eat, live as ....., what are they made of, live on,

Cilia, solitary cells, shells of organic debris, hard substrate

28

Freshwater cilia and planktonic one

Paramecium, tinntinids : vase like Lorica built from sand grains

29

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

30

Cliffs of Dover are made by

Foraminiferans ooze

31

Which two are prokaryotic

Bacteria and archaea

32

Viruses are .....cellular .....agents with what two basic characteristics

Non, infectious
Not capable of rep. Without host cell
Nucleic acid core: DNA or RNA
