Supergroups of Eukaryotes
This supergroup contains members that have an "excavated" groove on one side of the cell body.
Excavata
Euglena is commonly found in pond water and has the ability to move toward light. Which clade does Euglena belong to?
The Euglenids
A group of protists that share a few characteristics, including membranous sacs called alveoli beneath their cell membranes
Alveolates
Also known as Mycetozoans, this group of protists produces fruiting bodies that aid in spore dispersal.
Slime moulds
Reduced mitochondria are called?
Hydrogenosomes
This supergroup is comprised of foram amoebas that use threadlike pseudopodia for movement and prey capture.
Rhizaria (of SAR)
An organism that contains modified mitochondria, many are parasites that contain two equal-sized nuclei and multiple flagella
Diplomonads
What is the largest and most complex algae?
Brown Algae
Fungi are closely related to which member of Unikonta?
Nucleariids (of the Opiskothonts)
These organisms combine autotrophy and heterotrophy
Mixotrophs
This supergroup contains red and green algae, along with its close relative, land plants.
Parabasalids have reduced mitochondria known as?
Hydrogenosomes
This clade includes important photosynthetic organisms with flagellum that appear as fine, hairlike projections.
Stramenopila
The feeding stage of the life cycle of slime moulds; contains a mass of cytoplasm with many nuclei that undergoes many mitotic divisions without cytokinesis.
Plasmodium
Spores that move by flagella
Zoospores
Animals evolved from what member of Unikonta?
Choanoflagellates
The best-known Parabasalids are?
Trichomonas vaginalis
What part of a sporozoite contains a complex of organelles specialized for penetrating host cells and tissues?
The apex
The feeding stage of the slime moulds. A group of solitary, haploid, single cells that form an aggregate that functions as a unit when food is depleted.
Cellular slime moulds
1000s of interlocking circles of DNA inside a mitochondrion that contains many copies of the mitochondrial genome
Kinetoplast
The four supergroups of Eukaryotes are?
Excavata, SAR, Archaeplastida, and Unikonta
Protists that are carried by the tsetse fly and cause sleeping sickness (Trypanosoma) belong to which clade?
Kinetoplastids
The brown algae is comprised of three specialized tissues (organs). What are they?
Holdfast (anchor), stipe (support), and blades (photosynthetic)
The Opiskothonts include?
Animals, Fungi, and several groups of protists (Nucleariids and Choanoflagellates)
Which life cycle of the protists is an example of alternation of generations?
Laminaria (brown algae)
