Protist Flashcards
The algae and the protozoa
Protista
Comprised of a single cell that may be flagellated or non-motile
Unicellular
Comprised of more than one cell, generally without any division of labor, that may be flagellated or non-motile
Colonial
Comprised of a chain of cells
Filamentous
Comprised of more than one cell, generally with division of labor, that may be flagellated or on-motile
Multicellular
Set of chromosomes from a single parent that is typically denoted as “N”
Haploid
Set of chromosomes from two parents and is typically denoted as “2N”
Diploid
Organic solvent-soluble photosynthetic pigment common to all plastid-bearing lineages and most Cyanobacteria
Chlorophyll a
Organic solvent-solvable photosynthetic pigment common to chloroplast bearing lineages and some Cyanobacteria
Chlorophyll b
Organic solvent-solvable photosynthetic pigment common to rhodoplast-bearing chromalveolates
Chlorophyll c
Water-soluble pigments common to all Cyanobacteria and all rhodophyta
Phycobilin
Organism that is capable of phtoautotrophy and chemoheteotrophy
Mixotroph
Reduction divison of cells with diploid. Nuclei that results in cells (typically 4) with haploid nuclei
Meiosis
Cell division that involves duplication of the nuclear material whereby the resulting daughter nuclei are separated into two daughter cells
Mitosis
Reproduction generally involving the Union of haploid gametes or opposite mating types
Sexual reproduction
Reproduction that does not involve gametes but leads to progeny or cells that are largely identical (clones) of the parent organisms or parent cell
Asexual reproduction
Symbiotic relationship in which one organism resides inside the body or cells of another organism
Endosymbiosis
Early advocate of a theory for the origin of eukaryotic cells through endosymbiosis
Lynn marquis
Photoautotrophic (chlorophyll a and phycobolins) lineage of prokaryotes that share a common ancestor with plastids that were acquired by endosymbiosis
Cyanobacteria
Plastid type of the “green” or virdiplantae lineage in the archaeplastida and which has been acquired by secondary endosymbiosis in some organisms like euglena and chlorarachnion
Chloroplast
Plastid type of the “red” or rhodophyta lineage in the archaeplastida and which has been acquired by secondary endosymbiosis in some organisms like the dinoflagellates, apicomplexans, bacillariophyta, and phaeophyta
Rhodophyta
Endosymbiosis in which a cyanobacterium (prokaryote) was acquired as an endosymbiont in the cell of a eukaryotic chemoheterotroph where the cyanobacterial endosymbiont eventually evolved into a plastid
Primary endosymbiosis
Endosymbiosis in which a plastid-bearing (photoautotrophic) eukaryote was acquired as an endosymbiont in the cell of a eukaryotic chemoheterotroph where the plastid (and sometimes a reduced nucleus) of the endosymbiont was retained to serve the new host
Secondary endosymbiosis
Bilflagellate members of the euglenozoa (excavat) that include photoautotrophic with chloroplasts acquired by secondary endosymbiosis and flagella wit crystalline rods
Euglendids
Flagellated members of the euglenozoa, some of which are parasites (eg trypanosoma), that possess mitochondria with distinctive mitochondrial DNA (kinetoplasts)
Kinetoplastida
Flagellated members of the excavata, some of which are parasites (eg giardia), that possess dikaryotic cells
Diplomonads
Cellular adaptation for ingestion of particles in protozoans
Oral groove
Eukaryotic super-group of photosynthetic and non-photosynthetic eukaryotic microbes that share common flagellated features
Excavata
Distinctive structure associated with flagella in the euglenozoa
Crystalline rod
Flagellated members of the excavata, some of which are parasites (eg trichomonas), that possess unique fibers at the base of the flagella
Parabasalids
Flagellated parabasalid that causes STD that is often mis-diagnosed as yeast infection
Trichomonas
Intestinal parasite in the diplomonad lineage
Giardia
Photoautotropohic euglenid that acquired a chloroplast by secondary endosymbiosis
Euglena
Member of the euglenozoa that exists as a blood parasite that causes trypanosomiasis (African sleeping sickness; chaga’s disease)
Trypanosoma
Unusual mitochondrial DNA observed in a group of protists that bear the same name (kinetoplastida)
Kinetoplast
Alliance within the excavata that includes euglenids and trypanosoma
Euglenozoa
Biting fly of central Africa that lives on the blood of vertebrate animals and is the vector for African sleeping sickness (trypanosoma)
Tsetse fly
Biting bug of South America that is vector for chaga’s disease
Reduviid bug
Trypanosomiasis brought on with the he bit of the tsetse bug
Sleeping sickness
Trypanosomiasis brought on with the bite of the reduviid bug
Chaga’s disease
