Lab 2 Flashcards
Protist
eukaryotes, everything except bacteria, plant, fungi, or animals
single-celled protists
all biological functions are carried out individually, have a nucleus and membrane-bound organelles
what has the most structural and functional diversity than any other group of eukaryotes?
protists
algae
photosynthetic protists
protozoa
heterotrophic protists
Phylum Euglenozoa
a type of excavata that is a diverse group of flagellated unicellular protists, including photosynthetic autotrophs and heterotrophs
Euglena
a type of phylum euglenozoa that is a flagellated unicellular photosynthetic protest commonly found in freshwater
Trypanosoma
type of phylum euglenozoa that is flagellated, unicellular parasite transmitted by insect vectors
Trypanosoma cruzi
type of Trypanosoma that is responsible for Chagas disease in south America that is transmitted by the bite of triatomine insect called the kissing bug
stramenopilia
a type of protists that has two different types of flagella
Phylum Heterokontophyta
a stramenopilia with one somooth flagella and one with small hairs, mostly marine
Diatoms
a phylum heterkontophyta that has a heavy glass-like case (frustule)
how are diatoms involved in the carbon cycle?
they bloom and are photosynthetic and when they die, they sink to the bottom which removes C02
when the temperature rises the diatoms…
die which means less CO2 is removed which contributes to global warming
phylum phaeophyla
a stramenopillia that is large, macroscopic, multicellular brown algae, have flagellated gametes, one smooth, one hairy
Laminaria
giant kelp, a phylum phaeophyla, has a tough root-like structure (nadfast), stem-like structure, and leaf-like structure (Blades)
where is laminaria found?
cold, coastal waters where it provides habitat for shelter, reproduction, and feeding for many generations
Alternation of generations
lifecycle virtually identical to land plants that laminaria uses
Alveolata
a type of protist that has a membraneous structure at the base of the flagellum
Phylum Dinoflagellata
an alveolata that make up a major component of marine phytoplankton, some have red pigments (carotenoids and a toxins) that grow in blooms and stain water red
blooms if carotenoids and a-toxins can cause…
major fish kills (red tides)
Peridinium
a phylum dinoflagellata that is microscopic, bullet-shaped, has two flagella, one running a groove around the middle of the cell called a girdling flagellum and one trailing flagellum
Ceratium
a phylum dinoflagellata that is found in freshwater, has now been reclassified
Phylum Cilliophora
an aleolata that is a group of unicellular, heterotrophic, aquatic protists that have cillia, and two nuclei
What were phylum cilliophora two nuclei?
one small diploid micronucleus and one large polyploid nucleus
Paramecium
a phylum cilliophora that is abundant found in freshwater, slipper-shaped, relatively large
