In coenocytic hyphae, __________.

Nuclei undergo mitosis w/out cytokinesis

The decline of amphibian populations is most probably due to a(n) ________ parasite.


Fungi that consist of a continuous mass containing hundreds or thousands of nuclei are known as __________.


What is the major feature of glomeromycetes?


What are arbuscules?

the tiny tips of glomeromycete hyphae that invade plant roots and branch into treelike structures within root cells, forming arbuscular mycorrhizae

Which choice below generally represents the correct order of events in fungal sexual reproduction?

1) plasmogamy 2) karyogamy 3) meiosis 4) germination

During what stage of fungal reproduction are diploid cells produced?


What clade do fungi belong to?


Ectomycorrhizal fungi __________.

form sheaths of hyphae over the surface of a plant’s roots and extracellular spaces of the root cortex

Arbuscular mycorrhizal fungi ___________.

form extending branching hyphae by invaginating through the cell wall of the roots

Two types of mycorrhizal fungi:

Ectomycorrhizal and arbuscular

Multicellular fungal bodies are composed of ___________.

Filaments called Hyphae

__________ shows that the ancestors of animals and fungi diverged into separate lineages 1-1.5 billion years ago.

Molecular clock analysis

It has been suggested that the fungal ancestor was a ___________.


Lichens are important pioneers in areas that have been burned by fires or destroyed by lava flows because __________.

they are important in the initial stages of soil formation

The asexual spores produced by members of the phylum Ascomycota are called __________.


The fungal groups that are paraphyletic—that is, a group of taxa that consists of a common ancestor and some, but not all, of its descendants—are the __________.

chytrids and the zygomycetes

Two of the most common mycoses (fungal infections) in humans are __________.

athlete’s foot and yeast infections

Fungi in the phylum Basidiomycota are the most important decomposers of wood because of their ability to break down __________.


Which fungi absorb nutrients from living organisms?

Both parasitic and mutualistic

A parasitic fungus that attacks rye plants produces a structure called a(n) ________.


The __________ clade includes 160 species, with most producing arbuscular mycorrhizae.


Molecular evidence suggests that fungi share a common ancestor with who?

Animals (both evolved from aquatic flagellated protists)

Fungi "eat" their food by ___________.

secreting digestive enzymes into the environment and then absorbing the smaller compounds into their bodies

How many ascropores do you observe in asci during sexual reproduction of Neurospora?


Where did these ascropores that we observed during sexual reproduction of Neurospora result from?

Meosis followed by mitosis

You discover a fungus growing on the remains of a decaying tree trunk and hypothesize that it is a basidiomycete fungus because it resembles a mushroom in shape and size. If your logic is correct, microscopic analysis of the tissue found in the stalk of this fungus will reveal the presence of __________.

Dikaryotic cells w haploid nuclei

What induces the dikaryotic mycelium to form compact masses that develop into basisiocarps (mushrooms)?

Environmental cues (rain and temperature changes)

What role do pheromones play in fungal sexual reproduction?

Fungi use these chemical signals to determine whether a potential sexual partner is of a suitable mating type.

What are haustoria?

specialized hyphae of both mutualistic and parasitic fungi; used to extract/exchange nutrients from their plant hosts

Hyphae with two nuclei per cell are called __________.


The zygosporangium _________.

develops a rough, thick-walled coating that can resist harsh conditions for months (metabolically inactive)

Fungal species are classified in a particular phylum based on __________.

the type of sexual structure they form

What is a fungus with no known sexual stage called?


Based on a genomic analysis of a mycorrhizal fungus and four nonmycorrhizal fungi, researchers were able to identify ___________.

protein-coding genes, genes for membrane transporters, and genes for small secreted proteins
