Concept explainers
To determine: Whether the given data support the hypothesis and if stump removal reduces effects of A. ostoyae.
Introduction: Parasitic
To determine: Whether the stump removal reduces the effects of A. ostoyae or not.
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.

- What term describes the close association of a fungus with the root of a tree? a. arhizoid b. a lichen c. a mycorrhiza d. anendophytearrow_forwardIf all of the saprophytic fungi in an ecosystem died, which of the following would be a likely short-term result? Group of answer choices Plants would not be able to absorb nutrients from the soil as effectively Dead plant material would be decomposed more quickly, releasing higher levels of CO2 Less carbon dioxide would be released into the atmosphere because dead plant material would not be decomposed Plants would be unable to absorb nitrogen as efficiently because their root symbiotic fungi would be unable to break gaseous nitrogen apart Plants would be unable to absorb nitrogen as efficiently because their root symbiotic fungi would be unable to break gaseous nitrogen apartarrow_forwardIs saguaro cacti a fungusarrow_forward
- Please help me, this is not a graded question, it is a practice problem.arrow_forwardA 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_forwardLichens are a mutualistic relationship between a fungus and an alga or cyanobacterium, or both. The diagram below shows their symbiotic relationship. What is the role of fungi in lichens?arrow_forward
- options for one: -parasitism -convergent evoulution -mutualism I believe Mycorrhizae is correct for 2 but please check the other options are: -mycelia -lichensarrow_forwardThe largest living organism on the planet is a fungus that covers 965 hectares of forest. That's the equivalence of 1,800 football fields. This organism lies below the ground in a huge mat of what structure? O haustoria arbuscles hyphae myceliaarrow_forwardSaprophytes is kind of free-living organism that establishing and multiplying themselves in hosts O False O truearrow_forward
