Question 1

Crustose,fruticose,and foliose are varieties of

Accepted Answer

Crustose, fruticose, and foliose are growth forms of lichens. Lichens are symbiotic associations between fungi and algae or cyanobacteria. The crustose lichens have a smooth or crusty appearance, fruticose lichens have a shrubby or branching appearance, and foliose lichens have a leafy or lobed appearance.

Accepted Answer

The answer of Which of the fungal groups is mismatched...

Question 3

Species of ________ are known to consume jet fuel and wall paint.

Accepted Answer

Sac fungi, specifically certain species of Aspergillus and Penicillium, are known to degrade hydrocarbons found in jet fuel and can also consume components found in wall paint.

Question 4

Which of the following statements about mycorrhizae is/are true?

Accepted Answer

The answer of Which of the following statements about mycorrhizae...

Question 5

Yeasts

Accepted Answer

All of the choices are correct. Yeasts belong to the phylum Ascomycota, reproduce asexually by budding, and are commonly used in the production of beer, wine, and bread.

Question 6

Poisonous or physiologically active chemicals found in various fungi include all of the following EXCEPT

Accepted Answer

Digitoxin is not found in fungi, it is a cardiac glycoside found in plants such as foxgloves. Muscarine and muscaridine, psilocybin, and ergot alkaloids are all examples of poisonous or physiologically active chemicals found in various fungi.

Question 7

The answer of The organism pictured here is a member...

Question 8

Accepted Answer

Mycorrhizal sac fungi that live in association with oak and beech tree roots are truffles.

Question 9

The organism pictured below is a member of Phylum ___________.

Accepted Answer

The answer of The organism pictured below is a member...

Question 10

Batrachochytrium dendrobatidis,which reproduces asexually through the production of zoospores,recently destroyed populations of harlequin frogs in Central and South America.It is a member of which phylum of fungi?

Accepted Answer

Batrachochytrium dendrobatidis is a member of the Chytridiomycota phylum of fungi, which includes aquatic and terrestrial species that reproduce through the production of flagellated spores called zoospores.

Question 11

Fungi are thought to have been the first kind of eukaryotic cells that evolved.

Accepted Answer

The answer of Fungi are thought to have been the...

Question 12

The part of a mushroom that we eat is usually the reproductive structure that supports the fruiting body.

Accepted Answer

The part of a mushroom that we eat is usually the cap, which is the reproductive structure that supports the fruiting body.

Question 13

Fungal infections are difficult to treat because

Accepted Answer

Fungal and human cells are both eukaryotic and share many similarities, making it difficult to design antifungal medications that do not harm human cells. This makes fungal infections more difficult to treat compared to bacterial infections, which have significant differences in cell structure compared to human cells. While fungal infections may also have long latent periods, and resistance can develop over time, these factors are not unique to fungi and do not solely explain why fungal infections are difficult to treat.

Question 14

A normal inhabitant of the vaginal tract that causes "yeast infections" under certain circumstances is Saccharomyces.

Accepted Answer

The normal inhabitant of the vaginal tract that causes "yeast infections" is actually Candida, not Saccharomyces. Saccharomyces is a non-pathogenic yeast commonly used in baking and brewing.

Question 15

__________,a black mold that grows well on building materials,causes "sick building syndrome" in those who have been chronically exposed to its toxins.

Accepted Answer

Stachybotrys is known as "toxic black mold" and is known to produce mycotoxins that can cause health issues in those exposed to it for prolonged periods of time. It is commonly found in water-damaged buildings and has been associated with "sick building syndrome." Histoplasma, Candida, and Aspergillus are all types of fungi but do not cause the specific health problems associated with Stachybotrys.

Question 16

The fungi that parasitize cereal crops such as corn,wheat,oats,and rye are the

Accepted Answer

Rusts and smuts are types of fungi that parasitize cereal crops such as corn, wheat, oats, and rye. Stinkhorns, yeasts, truffles, and lichens are not known for parasitizing cereal crops.

Question 17

When the cap of an average gilled mushroom is cut off and placed on paper,a spoke-like print eventually appears on the paper under the cap.This powdery material would be

Accepted Answer

The powdery material that appears under the cap of a mushroom is known as the spore print. Basidiospores, which are produced on the basidia located on the gills of the mushroom cap, are responsible for creating the distinctive pattern on the spore print.

Question 18

Determine which of the following scenarios would be most likely to occur if the cyanobacteria was removed from a lichen.

Accepted Answer

Cyanobacteria in lichens are responsible for photosynthesis and produce nutrients that are used by fungal cells. If the cyanobacteria were removed, the fungal cells would lose this source of nutrition and would likely suffer. The other choices are not directly related to the presence or absence of cyanobacteria in the lichen.

Question 19

Which of the following information provides the strongest evidence to support the evolutionary relatedness between fungi and animals?

Accepted Answer

Molecular data showing a similarity in DNA/RNA base sequences is the strongest evidence to support evolutionary relatedness between two species. This indicates that both animals and fungi share common ancestry and have evolved from the same ancestor. Possessing a cell wall made of chitin or being heterotrophic or having flagella are only shared characteristics that may have developed independently and cannot alone provide the evidence for evolutionary relatedness.

Question 20

Which is NOT a correct association of a fungus and product?

Accepted Answer

Rusts and smuts are types of fungal plant diseases and are not associated with truffles, which are edible fungi.
