Protists Flashcards
Any eukaryotic organism that is not an animal, plant, or fungus. they do not form a natural group, or clade, but an artificial grouping of several independent clades that evolved from the last eukaryotic common ancestor.
Protists
The engulfment of one cell within
another such that the engulfed
cell survives, and both cells
benefit
endosymbiosis
This person developed endosymbiotic theory
Lynn Margulis, American Biologist 1960s
asymmetrical, single-celled
organisms with a feeding
groove “excavated” from
one side
Excavata
What group contains the subgroups: Diplomonads, Parabasalids and euglenozoans?
Excavata
Examples from this group are: Giardia lamblia, Trypanosoma brucei
Excavata
This means that they share a common ancestor
Monophyletic
derived from a common
ancestor that engulfed a
photosynthetic red algal cell,
which itself had already
evolved chloroplasts from an
endosymbiotic relationship
with a photosynthetic
prokaryote
Chromalveolata
Examples from this group are: dinoflagellates, Plasmodium, Paramecium, diatoms, brown algae, golden algae
Chromoalveolata
What group contains the subgroups: alveolates and stramenopiles?
Chromoalveolata
It includes many of
the amoebas, most of
which have threadlike
or needle-like
pseudopodia
Rhizaria
It is a temporary arm-like projection of a eukaryotic cell membrane that is emerged in the direction of movement.
pseudopodia
Which group includes the subgroups: pseudopods, forams, and radiolarians?
Rhizaria
Examples from this group are: amoebas, Ammonia tepida
Rhizaria
It was from a common
ancestor of these
protists that the land
plants evolved
Archaeplastida
What group contains the subgroups: red algae and green algae?
Archaeplastida
Examples from this group are: Volvox aureus, Caulerpa taxifolia
Archaeplastida
They characteristically
exhibit pseudopodia
that extend like tubes
or flat lobes
Amoebozoa
Which group contains the subgroups: slime molds, other unicellular
amoeba-like
organisms that are
free-living or
parasites?
Amoebozoa
include the animal-like
choanoflagellates,
which are believed to
resemble the common
ancestor of sponges
and, in fact, all animals
Opisthokonta
They are believed to resemble the common ancestor of sponges, and all animals.
Choanoflagellates
An organism that can create their own food
Photosynthetic
An organism that gains energy from other organisms
Heterotrophic
Organelle which contains chlorophyll
Chloroplast
This is what makes plants or leaves green
Chlorophyll
Parasites that infect other organisms
Parasitic
