Q

what was the problem of the 5 kingdom

A

Monaera had two groups that are unrelated

23
Q

who are eukaryotes more closely related to?

24
Q

What makes a Eukaryote?

A

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)
