Summary Introduction
Introduction: When two organisms interact with each other in order to survive it is known as a symbiotic relationship. Both the organisms living in a symbiotic relationship gain equal benefits. Mutualism, competition, parasitism, and commensalism are four main types of symbiotic relationships. When two species choose to live together it is known as facultative symbiosis and when two species live together in order to survive it is known as obligate symbiosis.

- The nutrition of some plants is enhanced by a mutually beneficial association between a root and a fungus. The association is known as _________. a. root nodule c. root hair b. mycorrhiza d. hyphaarrow_forwardThe waxy layer that covers aerial parts of plants is the (a) cuticle (b) archegonium (c) protonema (d) stoma (e) thallusarrow_forwardYou have been asked to consult for a biotech company that is seeking to understand why some fungi can live in very extreme environments, such as the high temperatures inside naturally occurring hot springs. The company has isolated two different fungal species, F. cattoriae and W. gravinius, both of which can grow at temperatures exceeding 95°C. The company has determined the following things about these fungal species (see attached image) By sequencing and examining their genomes, the biotech company hopes to understand why these species can live in extreme environments. However, the company only has the resources to sequence one genome, and would like your input as to which species should be sequenced and whether you believe a shotgun strategy will work in this case.arrow_forward
- Mutualistic associations between fungi and the roots of plants are called (a) lichens (b) mycorrhizae (c) pathogenic associations (d) parasitic haustoria (e) mycotoxic symbiosesarrow_forwardThe fungus Botrytis cinerea is a pathogen of plants, and causes high losses of strawberry crops around the world. In Europe, most B. cinerea fungi are killed by fungicides (chemicals sprayed on the crops to kill the fungus). However, some B. cinerea are resistant, and continue to live even when exposed to fungicides. If the currently-used fungicides continue to be sprayed on strawberry crops in Europe, what is expected to happen? (Choose one.) a)The strawberries will eventually become larger and more resistant to fungicides. b)The strawberries will form a beneficial association (mutualism) with the B. cinerea, and both will be resistant to the fungicides. c)Strawberry plants will preferentially be colonized by B. cinerea that are not resistant to fungicides. d) The proportion of B. cinerea that are resistant to fungicides will increase in the population over time, and these fungicides will no longer be effective at killing most of these fungi.arrow_forwardMycorrhizal fungi form obligate symbiotic relationships within plants. They are able to fix N2 into a usable form of nitrogen. In exchange, they receive nutrition from the plant. Which of the following is a true statement concerning mycorrhizal fungi? a) Finding a host plant is not crucial to their survival. b) They are a dominant species. c) They cannot survive without the host plant. d) They are considered plant parasites.arrow_forward
- Many fungal pathogens get food by causing plant cells to become leaky, releasing nutrients into the intercellular spaces. Would it benefit the fungus to kill the host plant in a way that results in all the nutrients leaking out? Explain.arrow_forwardSome plants are recognized by fungal pathogens on the basis of their stomatal pores. Which of the following would provide these plants immunity from fungal infection? a. Removing all of the stomata from the plant b. Changing the spacing of stomatal pores in these plants c. Reinforcing the cell wall in the guard cells of stomatal pores d. Increasing the number of trichomes on the surfacesarrow_forwardMycorrhizae enhance plant nutrition mainly by(A) absorbing water and minerals through the fungal hyphae.(B) providing sugar to root cells, which have no chloroplasts.(C) converting atmospheric nitrogen to ammonia.(D) enabling the roots to parasitize neighboring plantsarrow_forward
