Unit 6: Protists Flashcards
Which protist is this?
Oedogonium
Plant-like
Chlorophyta
What type of protist undergoes reproduction with gametes?
Chlamydomonas
(unicellular)
Which protist is this?
Difflugia
Animal-like
Sarcodina
Which protist is this?
Spirostomum
Animal-like
Ciliophora
During conjugation, what combines to form a new macronucleus in a recently conjugated paramecium?
2 micronuclei
(1 was its original and 1 is from the other protist)
What is the cellularity of most protists?
unicellular
During alternation of generations, what does the diploid sporophyte generation create during periods of environmental stress?
spores
(by meiosis therefore spores are haploid)
During alternation of generations, which generation is diploid?
sporophyte generation
What type of nucleus is exchanged during conjugation?
micronucleus
Which protist is this?
Volvox
Plant-like
Chlorophyta
Which protist is this?
Paramecium
Animal-like
Ciliophora
Which protist is this?
Euplotes
Animal-like
Ciliophora
During the sexual phase of reproduction with gametes, the mature protist produces ______ instead of zoospores
+ and - gametes
During reproduction with gametes and the asexual phase, what is formed during two consecutive rounds of mitosis?
4 zoospores
Which protists are unique in that they have shells made of silica?
Diatoms
Bacillariophyta
Which protists use pseudopodia?
Sarcodines
Which protist is this?
Actinosphaerium
Animal-like
Sarcodina
What type of sexual reproductive process involves the exchanging of DNA?
conjugation
Which protist is this?
Spirogyra
Plant-like
Chlorophyta
During alternation of generations, what do the haploid spores create during periods of environmental stress?
male and female gametophytes
(haploid spores divide by mitosis into haploid gametophytes)
Which protists are generally parasitic?
Sporozoans
During alternation of generations, what does the haploid gametophyte generation create during periods of environmental stress?
gametes
(by mitosis therefore they are haploid)
Which protist is this?
Didinium
Animal-like
Ciliophora
What structure in protists may have evolved over time into the anus?
anal pore
Which protist is this?
Amoeba
Animal-like
Sarcodina
Which protist is this?
Pandorina
Plant-like
Chlorophyta
During alternation of generations, what is the result of male and female gametes fusing together?
Zygote
(haploid gamete + haploid gamete = diploid zygote)
Which protist is this?
Blepharisma
Animal-like
Ciliophora
What are the three types of fungus-like protists
acellular slime molds
cellular slime molds
watermolds
What type of protist undergoes alternation of generation?
Ulva
(multicellular)
Which protist is this?
Stentor
Animal-like
Ciliophora
Where does the protista kingdom fall within the evolutionary tree?
How is giardiasis and amoebic dysentary contracted?
indirect transmission
Describe the internal anatomy of a flagellum or cilium
Which protists are multicellular?
Phaeophyta
Rhodophyta
Chlorophyta
Which protist is this?
Dileptis
Animal-like
Ciliophora
Which protist is this?
Eudorina
Plant-like
Chlorophyta
What do ciliates and zooflagellates have that aids in the absorption of food?
oral grooves and gullets
Which protist is this?
Euglena
plant-like
Euglenophyta
During reproduction with gametes, + and - gametes fuse to form a _____
zygote with hardens into a zygospore
How many protists do you start with and end with during conjugation?
2
Which protist is this?
Chlamydomonas
Plant-like
Chlorophyta
Which protist is this?
Arcella
Animal-like
Sarcodina
During alternation of generations, which generation is haploid?
gametophyte generation
What type of environments are ideal for protists?
Moist
freshwater, blood or marine environments
Which protista phylum is most similar to present day simple plants?
Chlorophyta
Which stage is diploid during the reproduction of gametes process?
Zygote/zygospore stage
Why is the meaning behind the chlorophyta phlyum name?
composed of chloroplasts and chloroplyll
Which two protist diseases are caused by sporozoans?
Malaria
Giardiasis
When zoospores mature and the environments remains favorable what do they create?
4 more zoospores
During alternation of generations, what does the diploid zygote become when conditions become favorable once again?
sporophyte
(diploid zygote divides by mitosis into a diploid sphorophyte)
