obtain nutrients SOLEY by absorption of organic matter from dead organisms
Forms spores but not seeds

17

Plantae consists of

A

contain chlorophyll and chloroplasts

18
Q

Animalia consists of

A

all animals derived from a zygote

worms are animals

19
Q

Stromatolites

A

fossilized photosynthetic prokaryotes that appear as masses of cells or microbial mats

20
Q

What are the three domains proposed by Woese

A

Eukarya
Bacteria
Archaea

21
Q

What are the three groups of archaea

A
methanogens (anaerobic)
extreme halophiles (high salt)
extreme thermophiles (high heat)
22
Q

Numerical taxonomy

A

the idea that increasing the number of characteristics of organisms that we observe increase the accuracy with which we can detect similarities among them

23
Q

Genetic homology

A

similarity of DNA

24
Q

Probes

A

single stranded DNA fragmetns

25
DNA hybidization
double strands of DNA of two organisms are split apart, and the split strands are allowed to combine
26
anneal
"bond to each other"
27
Protein profile
laboratory-prepared pattern of proteins found in a cell
28
Polycrylamide gel electrophoresis (PAGE)
how protein profiles are produced
29
Divergent evolution
occurs as certain subgroups of a species with a common ancestor undergo sufficient mutation to be identified as seperate species
30
Obligate intercellular parasties
they can only grow inside living cells
31
Mycoplasmas
no cell wall | sunny side up
