To determine: The tree species that was most often killed by A. ostoyae in control forests.
Introduction: Parasitic
To determine: The tree species that was least affected by A. ostoyae in control forests.
Introduction: Parasitic fungi attack plants and withdraw nutrients from them. Armillaria ostoyae (honey mushroom) is an example of fungal parasite. They attack the root systems of living trees. When the tree dies, the fungal parasite survives on the dead remains. The hyphae that grow from roots of infected trees and dead stumps invade roots of healthy plants leading to infection.

- Lichens could be correctly described as; A symbiotic association between an alga and a fungus A parasitic relationship between a fungus and an animal as symbiotic assocation betewen a fungus and the flies which disperse it's spores A symbiotic association between plant roots and a fungusarrow_forwardWhich of the following best describes the relationship between fig trees (Ficus carica), the ambrosia beetle (Euwallacea interjectus), and the fungus (Ceratocystis ficicola)? The beetles carry the fungus to the fig trees, which kills the fig trees. The fig trees require the fungus to survive, but the beetles eat and kill the trees. The beetles require both the fungus and the fig trees to survive. The fig trees infect the beetles with the fungus, which kills the beetles.arrow_forwardIf a symbiotic relationship between a fungus and its host plant is said to be commensal, what does this mean? Group of answer choices the fungi benefit, but the plant is unaffected the fungi are harmed and the plant benefits the plant is harmed and the fungi benefits both plant and fungi benefitarrow_forward
- options for one: -parasitism -convergent evoulution -mutualism I believe Mycorrhizae is correct for 2 but please check the other options are: -mycelia -lichensarrow_forwardPlease help me, this is not a graded question, it is a practice problem.arrow_forwardLichens are a mutualistic association of a fungus and either an alga or a cyanobacterium in which the fungus slowly engulfs the photosynthetic partner. the phototroph provides inorganic phosphorus to the fungus. the fungus helps collect sunlight for the photosynthetic partner. the fungus protects the photosynthetic partner from erosion.arrow_forward
- A plant that did not have mycorrhizae would most likely; Not be able to absorb as much water and nutrients as a plant that did Have a fungus that penetrates into the plants root cells to exchange nutrients Have a bacteria that lives in nodules on it's roots Be healthier than a plant that did have mycorrhizeaarrow_forwardIn a lytic infection, the host cell show symptoms faster. True False Saprophytes are organisms that use the complex molecules of dead or dying organisms for energy and nutrition. True Falsearrow_forwardFungi cell membrane contains sterol and ergesterol. Ergesterol synthesizing enzymes are drug targets for fungal treatment. True Falsearrow_forward
- Please help mearrow_forwardWhat is the symbiotic relationship between fungi and plant roots in which fungal hyphae penetrate the cell walls of the plants root cells? A-extomcorrhixa B vascular mycorrhizae C fungal rhizoids D arbuscar mycorrhiza E lichensarrow_forwardIn endomycorrhizal associations, the fungus enters the cell wall of the plant cells to share nutrients. Ture Falsearrow_forward
