Select the correct answer.Mycorrhizae are associations formed by fungi that grow on the roots of trees. These fungi penetrate into the roots of the trees. The trees produce energy through photosynthesis and share it with the fungi. The fungi act as decomposers, breaking down dead organic matter to provide nutrients for the trees to grow. What kind of a relationship is exhibited in this example? A. The fungi share a mutualistic association with the trees. B. The fungi are a parasite for trees. C. The fungi share a commensal association with the trees. D. The fungi are predators for the trees.

The relationship between mycorrhizal fungi that acquire nutrients for plants and plants in turn providing sugars for the fungi is an example ofMultiple choice question.commensalism.parasitism.mutualism.predation.

Many mushroom species establish mutually beneficial associations with plant roots, forming mycorrhizae. Through hyphal networks, fungi facilitate nutrient exchange, benefiting both mushrooms and host plants. This Mycorrhizal symbiosis profoundly influences plant growth, nutrient acquisition, and ecosystem stability. Mushrooms also exhibit captivating reproductive strategies and create enchanting patterns like fairy rings. Exploring mycorrhizal symbiosis unveils the vital role these organisms play in nutrient cycling, ecosystem dynamics, and the interconnectedness within the fungal kingdom.10 Mark For Review10According to the text, what is not true about Mycorrhizal symbiosis?A) It plays a crucial role in nutrient uptake and enhances plant growth and survival.B) Mycorrhizal symbiosis contributes to soil health and ecosystem functioning.C) Mycorrhizal symbiosis has implications for ecological restoration and interconnectedness in the ecosystem.D) It makes use of hyphal networks to demonstrate captivating reproductive strategies for mushrooms in the form of fairy rings.

Text 1In separate studies, Joanna Weremijewicz and colleagues and Sanâa Wahbi and colleagues examined whether plants transfer nutrients to one another using a common mycorrhizal network (CMN)—a lattice of fungal strands in the soil. Weremijewicz and colleagues excluded all pathways other than the CMN by using barriers to keep the plants’ root systems separate while allowing mycorrhizal strands through—a crucial step Wahbi and colleagues’ study did not take.Text 2Weremijewicz and colleagues took the necessary precaution of separating the plants’ root systems (thereby excluding root-to-root transmission). However, any barrier used must allow the threadlikehyphae of a CMN to pass through, and this permeability would also allow liquids through. Thus, the researchers’ experimental design cannot ensure that any nutrient transfer observed can be attributed to a CMN and not to some other pathway.7 Mark For ReviewBased on the texts, the author of Text 1 and the author of Text 2 would most likely give the same answer to which question?A) Do plants that transfer nutrients through a root-to-root pathway also transmit nutrients via a CMN?B) Is there an available barrier material that can block roots and liquids while allowing fungal strands through?C) Are the barriers used in Weremijewicz and colleagues’ study sufficient to ensure that nutrient transfer could only occur via a CMN?D) Did Wahbi and colleagues’ study effectively exclude any nutrient pathway other than a CMN?
