Exam 31: Fungi

Zygosporangia are to zygomycetes as basidia are to

Which of these is a fungal structure that is usually associated with asexual reproduction?

Which of the following terms is correctly associated with fungi in general?

Figure 31.1 below depicts the outline of a large fairy ring that has appeared overnight in an open meadow, as viewed from above. The fairy ring represents the furthest advance of this mycelium through the soil. Locations A-D are all 0.5 meters below the soil surface. Responses may be used once, more than once, or not at all. -The symbiotic associations involving roots and soil fungi are considered

In septate fungi, what structures allow cytoplasmic streaming to distribute needed nutrients, synthesized compounds, and organelles throughout the hyphae?

Figure 31.1 below depicts the outline of a large fairy ring that has appeared overnight in an open meadow, as viewed from above. The fairy ring represents the furthest advance of this mycelium through the soil. Locations A-D are all 0.5 meters below the soil surface. Responses may be used once, more than once, or not at all. -Lichens are symbiotic associations of fungi and

The gray-black, filamentous, haploid mycelium growing on bread is most likely what kind of organism?

Figure 31.1 below depicts the outline of a large fairy ring that has appeared overnight in an open meadow, as viewed from above. The fairy ring represents the furthest advance of this mycelium through the soil. Locations A-D are all 0.5 meters below the soil surface. Responses may be used once, more than once, or not at all. -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?

The following questions are based on the description below. Rose-picker's disease is caused by the yeast, Sporothrix schenkii. The yeast grows on the exteriors of rose-bush thorns. If a human gets pricked by such a thorn, the yeasts can be introduced under the skin. The yeasts then assume a hyphal morphology and grow along the interiors of lymphatic vessels until they reach a lymph node. This often results in the accumulation of pus in the lymph node, which subsequently ulcerates through the skin surface, and drains. -All fungi share which of the following characteristics?

Members of this phylum produce two kinds of haploid spores, one kind being asexually produced conidia:

Mushrooms with gills have meiotically produced spores located in or on

Responses may be used once, more than once, or not at all. -What is the most probable location of the oldest portion of this mycelium?

What is the primary role of a mushroom's underground mycelium?

Members of this phylum form arbuscular mycorrhizae:

Please refer to the following information to answer the following questions. Diploid nuclei of the ascomycete Neurospora crassa contain 14 chromosomes. A single diploid cell in an ascus will undergo one round of meiosis, followed in each of the daughter cells by one round of mitosis, producing a total of eight ascospores. -Each of the eight ascospores present at the end of mitosis has the same chromosome number and DNA content (ng)as each of the four cells at the end of meiosis. What must have occurred in each spore between the round of meiosis and the round of mitosis?

When a mycelium infiltrates an unexploited source of dead organic matter, what are most likely to appear within the food source soon thereafter?

The following questions are based on the description below. Rose-picker's disease is caused by the yeast, Sporothrix schenkii. The yeast grows on the exteriors of rose-bush thorns. If a human gets pricked by such a thorn, the yeasts can be introduced under the skin. The yeasts then assume a hyphal morphology and grow along the interiors of lymphatic vessels until they reach a lymph node. This often results in the accumulation of pus in the lymph node, which subsequently ulcerates through the skin surface, and drains. -Which of the following cells or structures are associated with asexual reproduction in fungi?

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

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?
