both benefit |
|
commensalism |
one benefits
the other isn't helped nor harmed |
|
parasitism |
one suffers
other benefits |
|
autotroph |
can make their own food |
|
phototroph |
use photosynthesis to make food |
|
heterotroph |
get organic molecules from others via ingestion/ feeding |
|
oold taxonomy main characteristic |
locomotion |
|
cilia + flagella |
undiplipodia
have internal structure called axoneme
cilia = flicker
flagella = whip - like |
|
9 + 2 microtubule arrangement |
9 longitudinal microtubules arrange around a central pair |
|
pseudopods |
extensions of the cytoplasm
used in locomotion |
|
ectoplasm |
rim of cytoplasm
outer part of cells
transparent rigid gel |
|
endoplasm |
inner fluid region
contain nucleus and organelles |
|
lobopodia |
large blunt extensions
contains endo andectoplasm |
|
limax form |
move like a whole body
instead of sending out arms |
|
filopodia |
thin sharp pointed extensions of ectoplasm only |
|
rhizopodia |
branched filaments only |
|
axopodia |
long thin pointed
supported by axial rods of microtubules |
|
nucleus |
membrane bound with numerous pores
contains DNA one or more nucleoi |
|
macronucleus |
larger
controls everything but reproduction |
|
micronucleus |
smaller
controls reproduction |
|
kinetosome |
basal body
located at base of axeoeme from where cilia and flagella grow |
|
hydrogenosomes |
without mitochondria
organelles have respiratory function without oxygen
don't have their own DNA |
|

contractile vacoule |
water is collected
emptied into canals then into a vesicle vesicle contracts to empty its contents to the outside serves as an osmoregulation organelle |
|
encystment |
formation of a cyst |
|
excystment |
escape from a cyst important for parasites to survive the transfer from one host to another |
