Both fungus-farming ants and their fungi can synthesize the same structural polysaccharide from the β-glucose. What is this polysaccharide?

Consider two hyphae having equal dimensions: one from a septate species and the other from a coenocytic species. Compared with the septate species, the coenocytic species should have

Immediately after karyogamy occurs, which term applies?

Which description does not apply equally well to both sexual and asexual spores?

Plasmogamy can directly result in which of the following? 1. cells with a single haploid nucleus 2. heterokaryotic cells 3. dikaryotic cells 4. cells with two diploid nuclei

After cytokinesis occurs in budding yeasts, the daughter cell has a

In most fungi, karyogamy does not immediately follow plasmogamy, which consequently

If all of their nuclei are equally active transcriptionally, then the cells of both dikaryotic and heterokaryotic fungi, in terms of the gene products they can make, are essentially

Which process occurs in fungi and has the opposite effect on a cell's chromosome number than does meiosis I?

Which of the following statements is true of deuteromycetes?

Asexual reproduction in yeasts occurs by budding. Due to unequal cytokinesis, the "bud" cell receives less cytoplasm than the parent cell. Which of the following should be true of the smaller cell until it reaches the size of the larger cell?

Many infected animals are induced by the parasitic microsporidians to develop huge cells, known as xenomas, which are full of spores. Given their large size, what should be true of the xenomas?

What are the sporangia of the bread mold Rhizopus?

Which of these paired fungal structures are structurally and functionally most alike?

You are given an organism to identify. It has a fruiting body that contains many structures with eight haploid spores lined up in a row. What kind of a fungus is this?

Which of the following has the least affiliation with all of the others?

Arrange the following from largest to smallest: 1. ascospore 2. ascocarp 3. ascomycete 4. ascus

Arrange the following from largest to smallest, assuming that they all come from the same fungus. 1. basidiocarp 2. basidium 3. basidiospore 4. mycelium 5. gill

Among sac fungi, which of these correctly distinguishes ascospores from conidia?

A fungal spore germinates, giving rise to a mycelium that grows outward into the soil surrounding the site where the spore originally landed. Which of the following accounts for the fungal movement, as described here?

In what structures do both Penicillium and Aspergillus produce asexual spores?

Chemicals, secreted by soil fungi, that inhibit the growth of bacteria are known as

In both lichens and mycorrhizae, what does the fungal partner provide to its photosynthetic partner?

Which of the following best describes the physical relationship of the partners involved in lichens?

If haustoria from the fungal partner were to appear within the photosynthetic partner of a lichen, and if the growth rate of the photosynthetic partner consequently slowed substantially, then this would support the claim that

When pathogenic fungi are found growing on the roots of grape vines, grape farmers sometimes respond by covering the ground around their vines with plastic sheeting and pumping a gaseous fungicide into the soil. The most important concern of grape farmers who engage in this practice should be that the

Which of the following terms refers to symbiotic relationships that involve fungi living between the cells in plant leaves?

If Penicillium typically secretes penicillin without disturbing the lichen relationship in which it is engaged, then what must have been true about its partner?

Sexual reproduction has never been observed among the fungi that produce the blue-green marbling of blue cheeses. What is true of these fungi and others that do not have a sexual stage?

Both fungus-derived antibiotics and hallucinogens used by humans probably evolved in fungi as a means to

A billionaire buys a sterile volcanic island that recently emerged from the sea. To speed the arrival of conditions necessary for plant growth, the billionaire might be advised to aerially sow what over the island?

Mycorrhizae are to the roots of vascular plants as endophytes are to vascular plants'

Which of the following conditions is caused by a fungus that is accidentally consumed along with rye flour?

The lifestyle of microsporidians is most similar to that of

For several decades now, amphibian species worldwide have been in decline. A significant proportion of the decline seems to be due to the spread of the chytrid fungus, Batrachochytrium dendrobatidis (Bd). Chytrid sporangia reside within the epidermal cells of infected animals, animals that consequently show areas of sloughed skin. They can also be lethargic, which is expressed through failure to hide and failure to flee. The infection cycle typically takes four to five days, at the end of which zoospores are released from sporangia into the environment. In some amphibian species, mortality rates approach 100%; other species seem able to survive the infection. 70) Apart from direct amphibian-to-amphibian contact, what is the most likely means by which the zoospores spread from one free-living amphibian to another?

All fungi share which of the following characteristics?

Which feature seen in chytrids supports the hypothesis that they diverged earliest in fungal evolution?
