how old are the earliest prokaryote fossils

3.5 billion years (stromatolite fossils) 

100

these bacteria have thick peptidoglycan layers

gram-positive bacteria

100

what supergroup are diatoms found in 

stramenopila

100

endosymbiosis describes how plant cell ancestors engulfed a _, which became the chloroplast

prokaryotic cell/cyanobacterium

100

what do seedless plants use to reproduce

spores/sporangia

100

how does lignin help plants live on land

provides rigid structural support

100

these tiny, thread-like tubes are the basic building blocks of fungi

hyphae

200

what's an example of an exotoxin

botulinum, tetanus, cholera, anthrax

200

corkscrew shaped (helical) bacteria with sheathed flagella

spirochaetes

200

green algae can be found in what supergroup 

archaeplastids

200

how old are the oldest land plant fossils

470 mya

200

what part of the plant becomes the fruit (angiosperms)

ovary (ovules become the seeds) 

200

why are flowers so successful despite their huge energy cost for plants

they are highly effective for ensuring pollination (both animal and wind-dispersal)

200

fungi are saprophytic heterotrophs, meaning

they absorb their food after digesting it outside their bodies

300

endotoxins are found in the

lipopolysaccharide layer (gram -) 

300

these bacteria have a thin layer of peptidoglycan, many modes of nutrient acquisition

proteobacteria

300

this supergroup includes slime molds 

unikonts

300

what type of plant was the first group to move onto land

nonvascular bryophytes (seedless, rootless) 

300

what is this 

anther (pollen producer)

300

what adaptation allows plants to exchange gases while minimizing water loss

stomata/guard cells

300

this group of fungi breaks down lignin, and produces mushrooms and puffballs

basidiomycetes

400

what type of archaea would you find in anaerobic swamps

methanogens

400

these autotrophic bacteria produce large amounts of oxygen

cyanobacteria

400

plasmodium (malaria) can be found in what supergroup

alveolata

400

what plants were dominant during the carboniferous, forming "coal forests" and cooling the earth 360-299mya

seedless vascular (ex. ferns) 

400

this is the seed-bearing structure that develops from the ripened ovary (the key to angiosperm success on earth!) 

fruit

400

non-flowering seed plants

gymnosperms

400

bread and fruit molds are examples of this group of fungi

zygomycetes

500

This stomach bacteria is notable for having both beneficial (prevent obesity and ibs) and harmful (causes ulcers) possible effects

Helicobacter pylori

500

obligate intracellular parasites

chlamydia
500

what group would foraminiferans be found in 

rhizaria

500

drove plant evolution by enabling lifelong growth and continuous generation of organs (leaves, flowers, etc) 

apical meristems

500

where does meiosis occur (flowering plants)

the anthers (male gametes) and the ovules inside the ovary (female gametes) 

500

why can the reduced genetic diversity of genetically modified crops be dangerous

vulnerable to disease/crop failure

500

this group of fungi have a symbiotic relationship with 80% of plants

glomeromycetes
