Question 1

The gills of a mushroom are specialized for
A) respiration.
B) food production.
C) defense.
D) reproduction.
E) water storage.

Accepted Answer

The gills of a mushroom are specialized for reproduction. They contain spores, which are used by the mushroom to reproduce and spread to new areas.

Question 2

Almost one-third of the species involved in mutualistic relationships known as lichens belong to the
A) Zygomycota.
B) Ascomycota.
C) Glomeromycota.
D) Blastocladiomycota.
E) Basidiomycota.

Accepted Answer

Lichens are a mutualistic relationship between a fungus (usually an Ascomycete) and an alga or cyanobacterium. Therefore, almost one-third of the species involved in mutualistic relationships known as lichens belong to the Ascomycota.

Question 3

Which statement about sac fungi is false?
A) Some species are yeasts.
B) They form reproductive structures called asci.
C) Their hyphae are segmented by septa.
D) Many of their species have a dikaryotic state.
E) They are classified according to the morphology of their ascomata.

Accepted Answer

Sac fungi are classified based on the morphology of their fruiting bodies, not their ascomata. Ascomata are the structures within which asci are formed.

Question 4

Common morels are classified as
A) Basidiomycota.
B) Ascomycota.
C) Zygomycota.
D) mycorrhizae.
E) lichens.

Accepted Answer

Morels are classified as Ascomycota because they belong to the phylum Ascomycota, which includes a diverse group of fungi that produce spores in sac-like structures called asci.

Question 5

A) mycorrhizae.
B) Ascomycota.
C) Basidiomycota.

Question 6

Assume that one haploid nucleus of a fungus with a dikaryotic life cycle contains 16 chromosomes.How many chromosomes would be present in the nuclei of a monokaryotic mycelium resulting from spore germination?
A) 4
B) 8
C) 16
D) 32
E) 64

Accepted Answer

In a fungus with a dikaryotic life cycle, a monokaryotic mycelium is haploid, meaning it contains the same number of chromosomes as the haploid nucleus, which is 16 chromosomes.

Question 7

Club fungi
A) have no visible fruiting structures.
B) have hyphae without septa.
C) have no sexual stage.
D) produce basidia within basidiospores.
E) form haploid basidiospores.

Accepted Answer

Club fungi, or Basidiomycota, form haploid basidiospores on structures called basidia.

Question 8

Reforestation may depend on soil fungi.Which fungus or fungi is/are beneficial for the establishment of seedlings in reforestation?
A) Lichens
B) Mycorrhizae
C) Yeasts
D) Aspergillus molds
E) Penicillium mold

Accepted Answer

Mycorrhizae fungi form a symbiotic relationship with the roots of plants, including trees, helping them to absorb nutrients and water from the soil. This makes them beneficial for seedling establishment in reforestation efforts. Lichens, yeasts, Aspergillus molds, and Penicillium mold do not play a significant role in this process.

Question 9

Baker's yeast is one species of the
A) Ascomycota.
B) Microsporidia.
C) Blastocladiomycota.
D) Basidiomycota.
E) mycorrhizae.

Accepted Answer

Baker's yeast is a member of the Ascomycota, which is a phylum of fungi that includes Saccharomyces cerevisiae, the species commonly used in baking and brewing.

Question 10

Assume that one haploid nucleus of a fungus with a dikaryotic life cycle contains 16 chromosomes.How many chromosomes would be present in one nucleus in a cell immediately after plasmogamy has occurred?
A) 4
B) 8
C) 16
D) 32
E) 64

Accepted Answer

The answer of Assume that one haploid nucleus of a...

Question 11

Which fungi are included in the same taxonomic group?
A) Cup fungi and bracket fungi
B) Truffles and morels
C) Amanita and powdery mildew
D) Black bread mold and pink bread mold
E) Dutch elm disease fungi and smut fungi

Accepted Answer

The answer of Which fungi are included in the same...

Question 12

Mosquitoes have developed resistance to most pesticides.Biologists have discovered that _______ and _______ can kill malaria-causing mosquitoes.
A) Ganoderma applanatum;Penicillium camembertii
B) Aspergillus tamari;Glomus mosseae
C) Beauveria bassiana;Metarhizium anisopliae
D) Aspergillus oryzae;Saccharomyces cerevisiae
E) Arthrobotrys dactyloides;Phyllactinia guttata

Accepted Answer

Biologists have discovered that Beauveria bassiana and Metarhizium anisopliae can kill malaria-causing mosquitoes. These two fungi are natural enemies of insects and have been found to be effective in controlling mosquito populations in several parts of the world. Unlike chemical pesticides, these fungi are safe for humans and the environment. Additionally, these fungi are able to infect mosquitoes that have developed resistance to other pesticides, making them a valuable tool in the fight against malaria.

Question 13

The cell walls of all fungi consist of the polysaccharide _______,which is also found in some animals.

Accepted Answer

The answer of The cell walls of all fungi consist...

Question 14

_______ fungi absorb their nutrition from dead organic material.

Accepted Answer

The answer of _______ fungi absorb their nutrition from dead...

Question 15

Because they are sensitive to atmospheric pollutants,_______ are good environmental indicators of air pollution levels.
A) sac fungi
B) lichens
C) club fungi
D) mycorrhizae
E) chytrids

Accepted Answer

Lichens are good environmental indicators of air pollution levels because they are sensitive to atmospheric pollutants such as sulfur dioxide and heavy metals. They are able to absorb these pollutants from the air and accumulate them in their tissues, leading to changes in their growth and survival. Therefore, the presence and abundance of certain types of lichens can provide valuable information about the level of air pollution in a given area.

Question 16

Which of the following belongs to the Basidiomycota?
A) Dutch elm disease fungus
B) Chestnut blight fungus
C) Powdery mildew
D) Green fruit mold
E) Smut fungus

Accepted Answer

Smut fungus belongs to the Basidiomycota, which is a phylum of fungi characterized by the presence of club-shaped fruiting bodies called basidia. The other options belong to different groups of fungi: A and B are examples of Ascomycota, C is an example of Erysiphales (also known as true mildews), and D is an example of Mucorales (also known as pin molds).

Question 19

A sexually produced spore that buds from the surface of a basidium is a(n)
A) zygospore.
B) ascospore.
C) sporangiophore.
D) basidiospore.
E) zoospore.

Accepted Answer

A basidium is a specialized structure found in basidiomycetes (club fungi) that is responsible for the production of sexually produced spores called basidiospores. Option A (zygospore) is a spore formed by the fusion of two haploid cells from different mating types, which is a process that occurs in zygomycetes. Option B (ascospore) is a spore produced inside an ascus, a sac-like structure found in ascomycetes (sac fungi). Option C (sporangiophore) is a stalk-like structure that supports a sporangium, a sac-like structure that produces asexual spores in some fungi. Option E (zoospore) is a flagellated spore that moves by means of one or more flagella. Zoospores are produced in various groups of fungi, including chytrids and some aquatic fungi.
