Lecture 9-Protista Flashcards
__________ are all eukaryotes that are not fungi, plants, or animals.
Protists
Protists are in the __________ group.
Paraphyletic
Protists are usually __________ and __________.
Unicellular, aquatic
__________ are nutritionally diverse.
Protists
Protists reproduce through __________ and __________ reproduction.
Sexual, asexual (meiosis and mitosis)
__________ have membrane organelles and a nucleus.
Protists
Protista range in size from _________ to __________.
Small, large
Original endosymbiotic events lead to the evolution of eukaryotes from prokaryotes, creating the __________.
Mitochondrion
Subsequent endosymbiotic events occurred that give rise to other organelles like __________.
Chloroplasts
Eukaryotic heterotroph engulfs photosynthetic cyanobacterium. Bacterium membranes are lost, organelles form:
Primary endosymbiosis
This lineage gives rise to the red and green algae.
Primary endosymbiosis
In both red and green algae lineages, multiple independent endosymbiotic events occur in:
Secondary endosymbiosis
The five eukaryotic supergroups are:
Excavata, Chromalveolata, Rhizaria, Archaeplastida, and Unikonta
This supergroup has highly modified mitochondria, multiple flagella, and ‘excavated’ feeding groove.
Excavata
This supergroup can cause numerous human diseases such as Chagas disease, sleeping sickness, non-bacterial gastroenteritis, and STD’s that increase HIV susceptibility.
Excavata
This supergroup is derived from secondary endosymbiosis of red algae.
Chromalveolata
__________ are the main component of plankton.
Dinoflagellates
