The incidence of fungal infections in human populations is low when compared to the frequency of diseases caused by bacteria, viruses, and protists.
Many plants grow significantly faster when they can form mycorrhizal associations with soil fungi. What fact explains this finding?
When researchers added radioactive phosphorus atoms to soil, plants grown in the presence of their symbiotic fungi received more of the radioactive phosphorus than did plants grown in the absence of fungi.
Which of the following statements correctly describes the evolution of fungi, according to current hypotheses?
Which conclusion drawn from the phylogeny shown below best explains these morphological traits in living fungal lineages: chitin in fungal cell walls, flagella in chytrid spores and gametes, and the storage of food through synthesis of glycogen?
Why are associations between ectomycorrhizal fungi and plant roots more common in a Canadian forest than in a Mexican swamp?
Using the known traits and lifestyle patterns of arbuscular mycorrhizal fungi (AMF), select the most likely AMF association from the choices below
A Glomeromycota species whose hyphae grow into the root cells of grassland plants in warm, low-phosphorus soils
Fungi that live in and on the leaves and stems of vascular plants are known as endophytes. Which of the following statements about endophytes is correct?
Some species of endophytes are commensals, meaning that the two species, endophyte and plant, coexist without substantial deleterious or beneficial effects.
Only small molecules can diffuse across the plasma membranes of hyphae. Macromolecules must first be broken down.
The leading hypothesis is that spore production is favored by natural selection when hyphae are under nutritional stress.
