Exam 17: Diversity of Eukaryotic Microorganisms

Which group of Eukarya has complicated the phylogenetics of the domain by first being thought of as ancient to the more recent view of them being highly derived eukaryotes?

Which group of amoebozoans is MOST likely to cause illness in humans?

Slime molds feed by phagocytosis and are more closely related to amoebas than to fungi.

Giardia are diplomonads which have nuclei that

There are two different mating types in the yeast Saccharomyces cerevisiae,and they can switch from one type to another.

Dinoflagellates have flagella that enable motility and occur in both freshwater and marine waters.

For a pure culture of Saccharomyces cerevisiae cells that were all derived from a single cell to mate,

Endolithic phototrophic communities are MOST common in ________ environments.

Despite oomycetes being called "water molds," they are phylogenetically distant from most other fungi.

Sporozoites observed in an insect's body likely indicate infection by an apicomplexan.

A thin,crescent-shaped organism with a single flagellum originating from a basal body and which folds back laterally across the cell would most likely be a member of the genus

ALL mushrooms are basidiomycetes.

Yeasts are immature fungal spores.

The amoebozoa use what structures for movement and feeding?

Stramenopiles are phototrophic microorganisms.

Hyphae are tubular cell walls that surround the cytoplasmic membrane.

Many parabasalids lack ________,which makes them different than most other eukaryotes.

Consider the development of a fossil record for a watershed.A current inventory of all species already has been taken.Which microorganisms might you first consider looking for with the objective of developing a microbial fossil record? Why? Also,what might depth profiling accomplish?

How does the genus Pfiesteria cause problems in both humans and fish?

All ciliates have cilia at some point during their life cycle,and some use the cilia not just for movement but also to direct food as well.
