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
