| 890691210 | Protists | diverse group of eukaryotic organisms that mainly live in aquatic enviornments | |
| 890691211 | type of protists colonies | loosely connected groups of cells | |
| 890691212 | type of protist coenocyter | multinucleated | |
| 890691213 | type of protist multucellular | composed of many cells | |
| 890691214 | pseudopodia | move by pushing out and pulling in cytoplasmic extensions | |
| 890691215 | amoeba can | ingest or engulf food | |
| 890691216 | protists are | free living or symbiotic, ranging from mutualism to parasitism | |
| 890691217 | mutualism | both benifit | |
| 890691218 | commerslism | one benefits and the other is unaffected | |
| 890691219 | parasitism | one lives on or in the other | |
| 890691220 | symbiosis | intimate relationship between species | |
| 890691221 | protists produce | both sexually and Asexually, some produce only Asexually | |
| 890691222 | monophyletic group | evolved from common ancestor | |
| 890691223 | paraphyletic group | contains some, but not all of the desentants of a common eukaryotic ancestor | |
| 890691224 | zooflagellates | mainly unicellular heterotrophs, with spherical or elongated bodies | |
| 890691225 | characteristics of zooflagellates | move rapidly with whip like flagella, ingest food with mouth | |
| 890691226 | excavates | diplomonads and other zooflagellates | |
| 890691227 | discicristates | euglenoids and other zooflagellates | |
| 890691228 | diplomonads | with a deep excavated oral groove, one or two nuclei, live in oxygenfree enviornments | |
| 890691229 | (zooflagellate) trichonympha | specialized excavates with 100's of flagella, live in guts of termites | |
| 890691230 | Euglenoids | unicellular with flagella, reproduce Asexually, some are photosynthetic | |
| 890691231 | Alveolates | have alveoli, flattened vesicles under plasma membrance, contain cellulase plates with cilicates | |
| 890691232 | ciliates (alveolate) | move by hair like cilia, able to change shape due to fexible pellicle | |
| 890691233 | micronuclei | for sexual reproduction | |
| 890691234 | macronuclei | for cell metabolism and growth | |
| 890691235 | dinoflagellates (aveolates) | unicellular, some are colonial | |
| 890691236 | biflagellate | propel through water like a top | |
| 890691237 | photosynthetic | major producers in marine ecosystems, store enery reserves as oils or polysaacharides | |
| 890691238 | endosymbionts | live in the bodies or marine invertebrates | |
| 890691239 | apicomplexans | are spore forming parasites, lack structures for locomation, cause disease | |
| 890691240 | apical complax of microtubules | attaches apicomplexan to host cell, half of life is spent in one host and the other half is spent in another | |
| 890691241 | heterokonts | most have motile cells with two different kinds of flagella | |
| 890691242 | water molds | a body called mycelium, grows over dead organic material. Digesting and then absorbing it | |
| 890691243 | Phytophora ramorum | causes sudden oak death, and attacks other trees | |
| 890691244 | phytophthora infestans | causes light blight of potato | |
| 890691245 | Diatoms | mostly unicellular algae, few exist as colonies | |
| 890691246 | Golden Algae | found in fresh water and marine enviornments, unicellular biflagellate, Asexual reproduction | |
| 890691247 | Brown algae | multicellular, Kelp | |
| 890691248 | cercozoa | amoeboid cells, often have hard outer shells | |
| 890691249 | actinopods | obtain food with axopods, mostly marine plankton | |
| 890691250 | red algae | mostly multicellular seaweeds, sexual reproduction, incorporate calcium carbonate in cell walls | |
| 890691251 | green algae | single celled, colonial, multinucleated, and multicellular forming sheets |
