|
contractile vacuolepelliclestigma (eyespot)chloroplasts
|
| |
Photoreceptor in Euglena |
|
light sensitive organ or paraflagellar swelling (not pigmented stigma) |
| |
Name and order of: |
|
paramecium (hymenostome)
|
| |
trichocyst |
|
defencive extrusomes that form a fibrous cloud around the paramecium when attacked |
| |
|
describe the differences between fission and conjugation |
|
conjugation is sexual reproduction, individuals line up side to sidefission is asexual reproduction, splitting end to end |

|
benthic zone |
|
lowest level of a body of watercommon benthic organisms include formaminifermans, nematodes, and just about everything else we studied |
| |
|
(T/F) All coccideans are apicomplexians. |
|
True. Coccidia include toxoplasmosis (cat feces) and plasmodium (malaria) but not Gregarines (gut parasite of insects) which are also in apicomplexia. |
