- Mycorrhizal fungi live in the soil and interact with the roots of plants. Essentail nutrients (e.g. nitrogenous compounds) are taken from the soil by the fungi and transferred to the plant roots. The fungi extract carbohydrates from the plant roots. What type of interaction is occurring?arrow_forwardUse the Internet to find examples of chytrids, zygomycetes,ascomycetes, and basidiomycetes that cause diseases in plants oranimals. How does each fungus infect a host and spread to new hosts?What can humans do to fight each disease? What are the costs andbenefits of doing so?arrow_forwardWhat are mycorrhizae? Discuss the different types in detail and give two examples of fungi that form mycorrhizae with economically important plants.arrow_forward
- What are mycorrhizae? and what are the different types of mycorrhizae, mention two examples of fungi that form mycorrhizae with economically important plants.arrow_forwardName and describe several key innovations in theevolutionary history of fungi that allowed them to move fromwater to land.arrow_forwardHow do pathogenic fungi colonize plants? Differentiate between the approaches utilized by saprophytes and biotrophs.arrow_forward
- What are some ways in which the relationship between a plant root and a mycorrhizal fungus is mutualistic?arrow_forwardWhich of the following is true of mychrrhizae? 1. The fungal hyphae of ectomycorrhizae form arbuscles. 2. Ectomycorrhizae penetrate the cytoplasm of root cells. 3. Endomycorrhizal fungal hyphae form a dense mantle ensheathing roots. 4. Ectomycorrhizae are found in many crop plants such as wheat and maize. 5. Ectomycorrhizal fungal hyphae form a dense mantle ensheathing roots.arrow_forwardDescribe two ways in which fungi differ from otherheterotrophic organisms in how they obtain and digest theirfoodarrow_forward
