Flashcards in LEC 9/22-24 Protista Deck (54):
1

Fact

scientific names are standard and recognized internationally

2

Fact

scientific name has a two-word latin name

3

What are the 2 parts of a scientific word?

1st is the Genus to which the organism belongs, 2nd work represents the Species

4

classification system (purpose)

brings logic and order to the study of living things

5

characteristics used for classification are:

characteristics that reflect the relationship between the species and shared derived characters

6

Mnemonic for King Philip..

Did King Philip Come Over For Great Sex?

7

Answer for Mnemonic

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

8

Classification for humans

D: Eukarya, K: Animalia, P: Chordata, C: Mammalia, O: Primates, F: Hominidae, G: Homo, S: H. sapiens

9

key events in life's history

3.5 billion yrs ago oldest fossilized bacteria

10

key events in life's history

2.1 billion yrs ago eukaryotes appeared

11

Prokaryotes

smaller, simpler, most do not have membrane-enclosed organelles, bacteria and archaea

12

Eukaryotes

Larger, more complex, membrane-enclosed organelles, protists, plants, fungi, animals

13

Key event in life's history

1.5 billion yrs ago multicellular eukaryotes multicellularity evolved several types giving rise to plants, fungi and animals

14

key event in life's history

500 million yrs ago, " cambrian explosion" diversification of animal forms, plants and animals move on to land.

15

key event in life's history

humans appeared in less than 0.2 second ago

16

Theory of endosymbiosis

explains the origin of eukaryotic cells from prokaryotic ancestors

17

fact

first multicellular organisms were colonies

18

Tor F

did the cambrian explosion give rise to most of the animal Phyla

19

classification is a work in progress

classification is constantly changing as we lerarn more abt orgainsms through new technology

20

Carl Linnaeus 1758

only two kingdom classification: Plantae and animalia

21

5 kingdom

Plantae, Fungi, Animalia, Protista, Monera

22

what was the problem of the 5 kingdom

Monaera had two groups that are unrelated

23

who are eukaryotes more closely related to?

Archea

24

What makes a Eukaryote?

unique cytoskeleton, flagella, endomembrane system, mitochondria, unique ribosomes

25

kingdom Plantae

autotrophs

26

Kingdom Animalia

Heterotrophs by ingestion

27

kingdom plantae

heterotrophs by ingestion, eat for engery

28

kingdom fungi

heterotrophs by absorption

29

Protista

is a paraphyletic clade

30

Protist diversity

result from endosymbiosis of unicellular algae

31

how did the endosymbiosis that resulted in chloropasts differ from the endosymbiosis that led to protist diversity

Red and green alga, phagocytes a eukaryote

32

algae are distinguished by

photosynthetic pigments, cell wall components, energy storage.

33

archaeplastids

include red algae, green algae and land plants

34

autotrophic include

unicellular, unicellular colonial or multicellular species

35

phylum rhodophyta

red algae

36

phylum chlorophyta

green algae

37

phylum charophyta

green algae

38

archaeplastids

phylum chorophyta

39

phylum chlorophyta

green color (chlorophyll), unicellular, colonial and Multi, cell wall (cellulose) store glucose as starch

40

archaeplastids

phylum rhodophyta (red algae)

41

phylum rhodophyta

red color (phycoerythrin) mask chlorophyll absorb blue&green light (deeper waters)

42

cell wall (phylum rhodphyta)

carrageenan (food industry, emulsifier) and agar (bacteria cultures)

43

Nori

sheets of porphyra

44

Stramenopiles

have hairy and smooth flagella

45

Latin "stramen" and "pilos"

straw and hair

46

Phylum Bacillariophyta

Diatoms (Stramenopiles)

47

Diatoms

brown in color, store food as lipids, cell wall (silica) most important organism on earth

48

Responsible for 70% of o2 production

diatoms

49

Phylum Oomycota

water mold (Stramenopiles)

50

Phylum Oomycota

unicellular, decomposes dead plants&animals (freshwater), parasitic on fish skin, and caused famine in ireland 1800

51

Alveolates

have sacs beneath the cell membrane

52

Phylum dinozoa

Dinoflagellates w/ flagella

53

Red tides

blooms of autotrophic dinoflagellates some of these can produce toxins

54

some form mutualistic relationships w/ corals

Dinoflagellates (phylum dinozoa)
