| Question | Answer |
|---|---|
| kingdom protista | domain eukarya |
| xtics of protist | 1. most are unicellular 2. some form colonies (multicellular) 3 free living aquatic orgamisms 4. asexual reproduction by most, some species engage in sexual reproduction 5 has more diversity than any other group 5. |
| when a protist is absorbed or ingested by another protist | secondary endosymbiosis |
| five main groups of protists | 1. excavata 2. chromalveolata 3. rhizaria 4. archaeplastida 5.unikonta |
| excavata | diplomonads. eg. giardia, euglenozoans |
| chromalveolata | dinoflagelates, apicomplexans eg. cause of malaria, ciliates, gold &brown algae |
| archaeplastida | red algae& charohytes/green algae |
| unikonta | slime molds and amoeba |
| brown algae/kelp | produces thickener called algin |
| red algae | produces sugar |
| green algae | ancestors of todays land plants |
| diatoms | small, unicellular, produce toxins, make hydrocarbons |
| dinoflgellates/plankton | major marine food source |
| water molds | freshwater decomposers |
| phylum archaezoa | 1. giardia- backpackers diarrhea 2. trichomonas-sexually transmitted UTI |
| phylum amoebazoa | entamoeba histolitica balamuthia- encephalitis |
| phylum ciliophora | balantidium- dysentary |
| phylum apicomplexa | worst of all cryptosporidium &cycospora- diarrhea isospora-coccidiosis plasmodium toxoplasma-toxoplasmosis |
| phylum euglenozoa | leishmania-leishmaniasis trypanosoma- african sleeping sickness |
| ciliate | complex eukaryotic cell, eg. paramecium |
| zooplankton | main food for marine, fresh water amphibians, eg. euglenoids and flagellates |
| trichonymphs | excavates that live in the gut of termite/ digest the wood they eat |
| water molds | caused the irish potato famine |
| slime molds | plasmodium and amoeboids form colonies |
| red and green algae | photsynthetic, multicelular |
| diatoms | unicellular,brown and yellow algae |
| protozoa | firts animal, reproduce asexually; fission, budding or schizogamy |
