Bio Lecture 3-27

Front 1

chemoheterotrophs

Back 1

consume organic molecules for energy and carbon

Front 2

decomposers

Back 2

recycle waste materials

Front 3

bioremediation

Back 3

use of organisms to remove pollutants from water, air, or soil

Front 4

nitrogen fixation

Back 4

bacteria are able to break triple bound of N( three lines) forming ammonia reduces N2 to NH3 produce enzymes called Nitrogenase N fixation is anaerobic
symbiosis with legumes( fabaceae)
plants produce leghaemoglobin which binds (removes) oxygen

Front 5

characteristics of protists

Back 5

single celled, some colonial, or filamentous
multicellular: red, brown, and algal protists
cyst: dormant form w/ resistant outer covering in which metabolism stops

Front 6

protozoans "little animals"

Back 6

heterotrophic "animal like" protists
classification is based on how they move
digest food in vacuoles

Front 7

chlorophyta

Back 7

green algae are generally acquatic in freshwater environments and often multicellular
photosynthetic
charalikely the ancestor
single celled, colonial, or filamentous

chlamydomonas is a well known genus

Front 8

choanoflagellida

Back 8

most like the ancestor of the animals
contain a single emergent flagellum surrounded by a funnel- shaped, contractile solar
nhnn

Front 9

fungal protists

Back 9

oomycota: "water molds"
forms cottony tufts
causes crop damage in grapes, potatoes

Myxomycetes: "slime molds

Front 10

brown algae

Back 10

cell wall have align( stabilizer in food, an emulsifier

Front 11

red algae

Back 11

used to make agar( used as a gelatin to stabilize a petri dish)
used as food additive: carregeenan ( increase viscosity_

Front 12

diatoms

Back 12

filtering agents, abrasives and soil additives to decrease pH

Front 13

dinoglagellates

Back 13

kill ocean fisheries
strong toxin used to treat cancer
