18 Questions
What is the name of the protist causing malaria?
Plasmodium
In which large group does Plasmodium belong?
Apicomplexa
What is the primary food source at the base of the freshwater food chain?
Diatoms
Which protist releases a large amount of energy into planktonic food webs?
Dinoflagellates
Which protist helps white blood cells fight disease?
Amoeba
Which protist is motile and free-living?
Amoeba
What is an example of endosymbiosis in animals mentioned in the text?
Termites & their protozoan gut inhabitant
In bioaccumulation, what accumulates inside living organisms?
Toxins or toxic chemicals
What is biomagnification primarily associated with?
Increasing toxin levels
Which of the following best defines an endocrine disruptor?
A chemical that disrupts normal endocrine system functions
Why does Plasmodium continue to pose a great risk to human health according to the text?
Despite modern medical advances, it has developed resistance
What is one example of Plasmodium's resilience mentioned in the text?
Evolution of resistant varieties of Anopheles mosquitoes
What is the difference between primary and secondary endosymbiosis in terms of mitochondrial and plastid evolution?
Primary endosymbiosis involves the uptake of a free-living bacterium by a heterotrophic eukaryote, while secondary endosymbiosis involves the engulfment of a photosynthetic eukaryote by another eukaryote.
Which statement accurately describes the relationship between algae and the evolution of mitochondria and plastids?
Algae were the original hosts of mitochondria, while plastids evolved from cyanobacteria within algae.
What evidence supports the theory that mitochondria were acquired before plastids in eukaryotic evolution?
The DNA of plastid genes in algae is similar to that of cyanobacteria, indicating a later acquisition of plastids.
How has advancements in systematics impacted the classification of Protista as a kingdom?
The kingdom Protista was dissolved due to new evidence suggesting its groups have ancestors in common with other kingdoms rather than with each other.
Why is it inaccurate to categorize Protista into one cohesive group based on evolutionary classification?
Protista groups have diverse ancestors from different kingdoms rather than sharing a common ancestry with each other.
What evidence supports the claim that all eukaryotes studied so far have either mitochondria or modified versions of them?
Identification of common mitochondrial structures across diverse eukaryotic species through genetic analyses.
Test your knowledge on how Plasmodium causes the resurgence of malaria by hiding inside human cells and changing its surface proteins. Identify examples of protists and their large groups.
