A scientist is interested in genetically engineering a fungus that has a limited reproductive process so that it does not accidentally cross breed with other fungi in the laboratory. Which process should be disrupted to hinder fungal reproduction? a) None of these b) Mycelium formation c) Spore formation d) Nutrient absorption e) Septa formation

Why are fungi important decomposers? They produce many spores They can grow in many different environments They produce mycelia They recycle carbon and inorganic minerals by the process of decomposition.

What term describes the close association of a fungus with the root of a tree? a rhizoid a lichen a mycorrhiza an endophyte

Why is the large surface area of the mycelium essential for nutrient acquisition by fungi?

Figure 11.9 If a mutation occurs so that a fungus is no longer able to produce a minus mating type, will it still be able to reproduce?

The wall dividing individual cells in a fungal filament is called a thallus hypha mycelium septum

Conjugation between two Paramecia produces total daughter cells. 2 4 8 16

Figure 24.14 Which of the following statements is true? A dikaryotic ascus that forms in the ascocarp undergoes karyogamy, meiosis, and mitosis to form eight ascospores. A diploid ascus that forms in the ascocarp undergoes karyogamy, meiosiis, and mitosis to form eight ascospores. A haploid zygote that forms in the ascocarp undergoes karyogamy, meiosiis, and mitosis to form eight ascospores. A dikaryotic ascus that forms in the ascocarp undergoes plasmogamy, meiosis, and mitosis to form eight ascospores.

Why are fungal insecticides an attractive alternative to chemical pesticides for growing food crops? Human consumption of fungal insecticides would not make a person sick, but ingestion of chemical pesticides can be harmful to humans A single fungal insecticide would kill a wider variety of insects than a chemical pesticide Fungal insecticides can eliminate both harmful insects and plant pathogens, while chemical pesticides only kill insects Fungal insecticides will decompose dying plants, enhancing the nitrogen content of the soil, while chemical pesticides are not decomposers.

The targets for anti-fungal drugs are much more limited than antibiotics or anti-viral medications. Why? There are more bacteria and viruses than fungi Fungi can only be targeted during sexual reproduction, while bacteria and viruses can be targeted at any point in their lifespan Fungi cause topical infections, while viruses and bacteria cause systemic infections Human cells are much more similar to fungi cells than bacteria or viruses.
