Flashcards in Lecture 9-Protista Deck (44):
1

__________ are all eukaryotes that are not fungi, plants, or animals.

Protists

2

Protists are in the __________ group.

Paraphyletic

3

Protists are usually __________ and __________.

Unicellular, aquatic

4

__________ are nutritionally diverse.

Protists

5

Protists reproduce through __________ and __________ reproduction.

Sexual, asexual (meiosis and mitosis)

6

__________ have membrane organelles and a nucleus.

Protists

7

Protista range in size from _________ to __________.

Small, large

8

Original endosymbiotic events lead to the evolution of eukaryotes from prokaryotes, creating the __________.

Mitochondrion

9

Subsequent endosymbiotic events occurred that give rise to other organelles like __________.

Chloroplasts

10

Eukaryotic heterotroph engulfs photosynthetic cyanobacterium. Bacterium membranes are lost, organelles form:

Primary endosymbiosis

11

This lineage gives rise to the red and green algae.

Primary endosymbiosis

12

In both red and green algae lineages, multiple independent endosymbiotic events occur in:

Secondary endosymbiosis

13

The five eukaryotic supergroups are:

Excavata, Chromalveolata, Rhizaria, Archaeplastida, and Unikonta

14

This supergroup has highly modified mitochondria, multiple flagella, and 'excavated' feeding groove.

Excavata

15

This supergroup can cause numerous human diseases such as Chagas disease, sleeping sickness, non-bacterial gastroenteritis, and STD's that increase HIV susceptibility.

Excavata

16

This supergroup is derived from secondary endosymbiosis of red algae.

Chromalveolata

17

__________ are the main component of plankton.

Dinoflagellates

18

Dinoflagellates are in the __________ supergroup.

Chromalveolata

19

__________ cause red tides, some of which produce harmful neurotoxins or deplete oxygen levels in water.

Dinoflagellates

20

__________ is loss of zoothanthellae.

Coral bleaching

21

When temperature _____, it causes coral bleaching.

Rises

22

__________ are bioluminescent.

Dinoflagellates

23

The supergroup __________ can cause human diseases such as malaria.

Chromalveolata

24

Malaria is caused by __________, in the Chromalveolata supergroup.

Apicomplexa

25

__________ contribute to almost 45% of ocean primary productivity, providing vast amounts of energy and oxygen.

Diatoms

26

Diatoms are in the __________ supergroup.

Chromalveolata

27

The supergroup __________ are amoeba-like with threadlike pseudopodia.

Rhizaria

28

The supergroup __________ are made up of parasites of plants and animals and make excellent index fossils.

Rhizaria

29

The supergroup __________'s main groups include red algae, green algae, and land plants.

Archaeplastida

30

The supergroup __________ helps with reef formation and are edible.

Archaeplastida

31

The supergroup __________ is made up of amoebazoans with tube-like pseudopodia.

Unikonta

32

The supergroup __________ can cause diseases such as amoebic dysentery and brain-eating amoeba.

Unikonta

33

__________ are usually photosynthetic.

Dinoflagellates

34

__________ leads to high protist diversity.

Endosymbiosis

35

__________ are pathogenic protists needing more than one host; causes Chagas.

Trapanosoma

36

__________ is the most common pathogenic protist infection in industrialized countries; increases HIV susceptibility.

Trichomonas vaginales

37

When there isn't enough information to resolve a node in a phylogeny, it's called a:

Polytomy

38

__________ is the most common intestinal parasite and the leading cause of non-bacterial gastroenteritis.

Giardia intestinalis

39

__________ are photosynthetic algae contained in silica "shells".

Diatoms

40

Largest, most complex type of algae.

Brown algae

41

Represents true algae.

Green algae

42

This type of algae photosynthesizes at great depths. It is important in reef formation. (Secretes carbonate)

Red algae

43

Another term for silica shells.

Radiolarians

44

Flagellated collar cells; closest protist relative to animals.

Choanoflagellates
