Cards

Term
Diplomonads and Parabasalids
Definition
no mitochondria, move with flagella, related to ancestral eukaryotes
Term
Diplomonads- special characteristic and example
Definition
have 2 nuclei, ex: Giardia intsetinalis
Term
Parabasalids- special characteristic and example
Definition
have undulating membranes, ex: STD Trichomonas Vaginalis
Term
Euglenozoa
Definition
asexual reproduction, have flexible pellica, some have chloroplasts, have flagella
Term
Example of Euglenozoa
Definition
Euglena
Term
Define Kinetoplastids
Definition
Have DNA maxicircles and minicircles,
One subgroup is trypanosomes, cause African Sleeping Sickness and Leishmaniasis,
hard to control b/c constantly change antigens on coat
Term
Alveolata
Definition
have flattened vesicles
Term
Examples of Alveolata
Definition
dinoflagellates, Apicomplexes, Ciliates
Term
Dinoflagellates
Definition
2 flagella, plates of cellulose or silica, some bioluminescent, symbiosis with corals-Zooxanthellae, cause red tide from toxin producing
Term
define apicomplexes
Definition
spore forming animal parasites, apical complex is unique arangement of organelles at one end of cell
Term
Example of Apicomplexan
Definition
Plasmodium, causes malaria, carried by mosquitos, asexual and sexual stages
Term
define ciliates
Definition
cilia arranged in rows or spirals around cell
Term
examples of cilia
Definition
paramecium, vorticella, stentor
Term
define macro and micronuclei
Definition
in ciliates- macro divide by mitosis, responsible for physiological funcions, micro divide by meiosis, involved in conjugation
Term
Stramenopila
Definition
unique fine hairs on flagella
Term
Examples of stramenopila
Definition
kelp, brown algae, diatoms, oomycetes
Term
brown algae
Definition
seaweed, alternate multicellular generations of diploid sporophytes and haploid gametophytes, secondary endosymbiosis-engulfed red algae with chlorophyll
Term
diatoms
Definition
unicellular with double silica shells, have two long grooves with vibrating fibrils
Term
oomycetes
Definition
parasites or detritivores (saprobes), aquatic, have two unequal flagella, caused potato famine
Term
Rhodophyta
Definition
red algae, uni and multicellular, no flagella or centriole, photosynthetic, sushi!
Term
ex of Protists without a clade
Definition
choanoflagellida, amoeba, foraminifera, slime molds
Term
choanoflagellida
Definition
animal ancestor, 1 flagella with contractile collar
Term
amoeba
Definition
pseudopods, engulf food particles
Term
foraminifera
Definition
heterotrophic marine protists, like tiny snails, unicellular, calcium carbonate-white cliffs of dover
Term
plasmodial slime mold
Definition
streaming multinucleated mass, feeding phase
Term
cellular slime molds
Definition
behave as separate amoebas until starved-> band together as slug or sporocarp-make spores
