Taxonomy
What are the 2 subkingdoms of Kingdom Protista?
Subkingdom Protozoa and Subkingdom Algae
Which organelle is responsible for digesting nutrients?

BONUS! 500 Points!
What is a pseudopod?
A "false-foot" structure that allows for a Sarcodina organism to move.
Explain how and why leaves change colors.
Chlorophyll in leaf breaks down due to colder temperatures and less light, revealing underlying pigments!
BONUS! 500 points!
Which phylum in Kingdom Protista has organisms that have flagella?
Phylum Mastigophora
Name the 3 modes of locomotion for organisms in Kingdom Protista.
Cilia, Pseudopod, and Flagella
Which organism causes malaria?
Plasmodium.
What is a spore?

What is the fluid in the center of an Amoeba called?
Endoplasm.
Which phylum performs longitudinal binary fission?
Mastigophora
Give three main characteristics of organisms in Phylum Sarcodina.
What is the purpose of the oral groove?
Ciliates use cilia to sweep food into the oral groove. Acts as the "mouth" of the organism. Also allows for DNA exchange during conjugation.
Which phylum contains the organism responsible for causing African Sleeping Sickness?
BONUS 200 Points: What is this organism's genus?
Mastigophora. Trypanosoma.
Define phagocytosis.
The process of an organism engulfing its food by surrounding it with the cell membrane.
What does the name "mastigophora" literally translate to?
Whip-bearer
Name all the phyla in Subkingdom Protozoa.
Sarcodina, Mastigophora, Ciliophora, Sporozoa
Which organelle is responsible for detecting light? What is the green pigment inside these organelles called?
Chloroplast. Chlorophyll.
Describe the life cycle of Plasmodium.
Lives in the gut of a mosquito. Spores enter the bloodstream of a human via saliva of mosquito. Replicate in the liver and enter red blood cells, causing them to burst. Blood can then be carried by mosquito to other humans.
What phylum in Subkingdom Protozoa have organisms that are photosynthetic?
Phylum Mastigophora (genus Euglena).
Which organism has 2 nuclei? Why do they need 2?
Paramecium. The cilia require a large amount of energy, so nuclei each perform specialized functions to allow for greater rate of metabolism.
