Exam 17: Diversity of Eukaryotic Microorganisms

The majority of basidiomycetes living in soil occur as

ALL mushrooms are basidiomycetes.

Which microbial group is responsible for massive amphibian die-offs worldwide?

Most fungi are aerobic chemoorganotrophs that decompose large molecular weight compounds by secreting extracellular enzymes.

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

What is an endolithic algal community? Where are these found,and how do they survive?

The endosymbiosis that formed mitochondria likely occurred after eukaryotes developed photosynthetic capabilities.

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

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

Divergence of the green and red algal lineages at least partially explains how two different primary endosymbiosis events occurred to form different chloroplast types in different taxa.

Ascospores are produced in all of the following taxa EXCEPT

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

The amoebozoa use what structures for movement and feeding?

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

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.

The function of the parabasal body is to
