|
protozoans
|
|
|
protoplasm: define and part of
|
differentiated into nucleus, cytoplasm, organelles/ Protozoans
|
|
|
Cytoplasm: define and part of
|
thin outer ectoplasm thick endoplasm containing mitochondria/protozoans
|
|
|
Protozoans are faculative anaerobes, obligative anaerobes
|
faculative anaerobes, they respire by taking in O2 and expelling Co2
|
|
|
Contractile vacuoles function and organism
|
regulation of osmotic pressure/elimination of waste, protozoans
|
|
|
locomotion in protozoans
|
flagella, cilia, pseudopodiy
|

|
methods of asexual reproduction in protozoans
|
binary fission, schizogony (multiple fission), endodyogeny (budding)
|
|

|
conjugation, syngamy
|
|
|
describe body shape of trematode
|
flattened and elongated except for schistosomes that are cylindrical
|
|
|
non-cellular integument : function/parasite
|
contains mitochondria and vacuoles, trematodes
|
|
|
method of attachment for trematodes
|
suckers or hooklets

|
|
movement of trematodes
|
layers of muscles beneath integument
|
|
|
snail intermediate host
|
trematodes, (also releases eggs)
|
|
|
nervous system: trematodes
|
two lateral ganglia near pharynx and nerve fibers throughout body
|
|
|
DO trematodes have body cavity?
|
No but have digestive tract with pharynx
|
|
|
flame cells: function
|
part of excretory system of trematodes which also includes connecting tubules and excretory pore
|
|
|
method of reproduction for trematodes

|
Ribbon like shape
|
Cestodes
|
|
|
anatomy of cestode:
|
scolex (head) with segments of proglottids forming a chain called strobilum
Scolex has grooves or bothria, sucking discs or rostellum armed with chitious hooks |
|
|
Cestode: tegument
|
contains mitochondria, vacuoles, inclusion bodies and digestive enzymes
|
|
|
Cestodes are faculative or obligitae anaerobes?
|
Faculative, can do anaerobic metabolism
|
|
|
cysticercus, coenurus, or echinococcus describe?
|
larval forms that are solid, vesicular or bladder like which form cysts in cestodes
|
|
|
reproduction: cestode
|
hermaphroditic, can CROSS FERTILIZE**between segments of same works or different worms
|
|
|
Elongated cylindrical worms
|

|
contains hooks, teeth lips or plates
|
|
|
Nematode digsetive tract:
|
elongated tube with oral cavity, esophagus, midgut, hindgut and anus
|
|
|
nematodes are anaerobic/aerobic both?
|
both, they are faculatative anaerobes
|
|
|
Nematode: excretory system:
|
two later canals that transverse worms body emptying into anus
|
|
|
nematode: circulatory system
|
none but body cavity fluid contains hemoglobin, glucose, proteins and salt and functions like blood

nematode: nervous system
|
anterior nerve rign of connected ganglia surrounding esophagus
|
|
|
nematode: reproduction
|
dioecious- male and female in different organisms, male and female systems very similar to humans
|
