Exam 17: Diversity of Eukaryotic Microorganisms

Compare and contrast the life cycles of the cellular and the acellular slime molds.

The accessory pigment phycoerythrin is dominant in the ________ group of algae,which mostly lack flagella,have multicellular lifestyles,and occur in marine waters.Those in particular which deposit calcium carbonate in coral reef systems are classified as ________ algae.

A fungal mycelium is a large accumulation of ________,which may appear dusty or fuzzy due to the presence of ________.

Mitochondria and chloroplasts have their own DNA but use the ribosomes of the host cell.

A geologist going through a sediment core is likely to find remnants of ancient calcium carbonate containing ________ and silica containing ________.

Spoilage of bread,which appears dark green-blue to black in color,is MOST likely caused by the fungus

Chytridiomycosis is thought to be associated with increases in environmental temperature associated with global warming.Design a series of experiments that would help to prove or disprove this hypothesis.

Some chrysophytes (or "golden algae")are actually chemoorganotrophs rather than phototrophs.

Unlike the 16S rRNA gene phylogenetics used to identify relatedness in Bacteria,the 18S rRNA gene is by itself unreliable for phylogeny of members in Eukarya.

Discuss the theory of secondary endosymbiosis and defend the theory by providing evidence that supports it.

The majority of basidiomycetes living in soil occur as

Oomycetes ("water molds")contain ________ in their cell walls,while most fungi have ________ in their cell walls.

Among protists,only the ciliates have a micronucleus and macronucleus where genes are located in two discrete areas within each cell for redundancy.

What are the MOST abundant biomolecules in a typical fungal cell wall?

Ascospores are produced in all of the following taxa EXCEPT

What would a fucoxanthin carotenoid stain be most useful in identifying?

Which statement BEST describes the habitats of the fungi?

Which algae are MOST closely related to plants?

The unusual ability for ________ being flagellated and motile enables ________.

Evidence of ________ supports the hypothesis that eukaryotes are derived from bacteria.
