multicellular

17
Q

What four things do alveolates possess, where do they live, and what do they include, and what can they cause

A

possession of alveolae- membrane-bound sacs found in the plasma membrane

mitochondria with internal tubes

include dinoflagellates, apicomplexans, ciliates

cellulose cell wall

2 flagella

marine

causes red tides

18
Q

What are apicomplexans?

A

parasitic organisms, example- malaria

19
Q

dinoflagellates (3)

A

unicellular

takes food

two flagella

20
Q

what two things do ciliates possess, where are they found, and an example?

A

possession of cilia

2 nuclei- macro and micronucleus

freshwater

ex- paramecium

21
Q

what is cilia? (2)

A

cellular organelles, short and grouped to function

used for locomotion to cruise

22
Q

What are rhizarians? (2)

A

capable of amoeboid movement, pseudopodia

includes forams, cercozoans, and radiolarians

23
Q

What are forams? (2)

A

lived in ancient times

left calcium carbonate tests-shells, that make up limestone

24
Q

Where are cercozoans found, and what do they do?

A

found in freshwater, salt water, and soil

able to engulf bacteria and protists

25
Q

What are radiolarians? (2)

A

have tests and pseudopdia with SiO2 tests

forms radiolarian ooze

26
Q

What do archiplastida include?

A

red algae, chlorophytes, charophytes, and land plants

27
Q

Red algae (3)

A

have phycoerythrin pigment

require current to bring gametes together

nori

28
Q

chlorophytes and charophytes (2)

A

green algae

fresh, but some like in marine

29
Q

charophyte (3)

A

closest living relative to plants

share enzymes with plants

has calcium carbonate in cell walls

30
Q

unikonta characteristics

A

myosin- muscle proteins

amoebozonas and opisthokonts

31
Q

amoebozoans (2)

A

move through pseudopodia- lobee and tubular

slime molds, tubulinids, entamoebas

32
Q

slime molds (2)

A

produce sporangia for reproduction

group together and function as a single multicellular unit during food shortage

33
Q

tubulinids (4)

A

amoebae with lobular pseudopodia

uses muscle fibers to move

changes from liquid to jelly tate to move

heterotrophs

34
Q

entamoebas (2)

A

parasitic

unicellular

35
Q

opisthokonts (3)

A

have internal walls in mitochondria that is flat

flagellated cells with a single flagellum

contains nuclearids, fungi, choanoflagellates, and animalia

36
Q

nucleariids (4)

A

unicellular

thread-like pseudopodia

similar DNA to fungi

moist soil and freshwater

37
Q

Choanoflagellates (4)

A

unicellular colonial protists

similar to sponges with similar proteins to hold cells together

found in sea nd freshwater

filterfeeders
