Introduction:
Fungi include organisms that are neither plants nor animals. They are the group of eukaryotic organisms that include yeasts, molds, and mushrooms. They are known to be the decomposers of dead organic matter in an ecosystem. Fungi get food by absorbing the nutrients from other organisms. They do not prepare their own food.

You 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.
Which of the following statements about fungi is FALSE?
O 1) They may cause human disease.
O 2) fungi are photosynthetic.
O3) fungi are eukaryotes.
O 4) Fungi include yeasts and molds.
O 5) Some fungi are unicellular.
Determine the ecological consequences that would occur if humans destroy all the fungi on Earth using a deadly fungicide.

- Assume you have an invasive fungus species growing in your backyard and you want to get rid of it. You decide to remove them from the ground by hand and dispose them in a corner because they will die off anyways. Few days later, you see even more fungi growing where you remove the original fungus. Why do you think that happened?arrow_forwardHow might life on Earth differ from what we know today if no mutualistic relationships between fungi and other organisms had ever evolved?arrow_forwardFungi are similar to animals by a) Their use of enzymes to digest food b) Their mode of reproduction c) Their ability to move d) Having a symbiotic relationship with algaearrow_forward
- In the early 1800s, potatoes became the main food staple for the people of Ireland. In 1845, a fungus native to South America, Phytophthora infestans, began to infect potato plants, causing potato blight and making the tubers inedible. Over the next several years, most of the potato plants in the country were destroyed by this invasive species. Which of the following statements correctly explains why the Irish potato famine occurred? The arrival of ships from South America led to human introduction of the disease. A drought across Ireland in 1844 led to more damaged potato plants that were susceptible to infection. An increase in trade with other European countries led to the introduction of plants that were already infected with the fungus. Ireland's climate became closer to that of South America, which allowed the fungus to infect potato plants and reproduce.arrow_forwardThe Fungi are a kingdom driven by their relationships with other taxa. I) What two major roles do fungi play? ii) Describe one example of a specific fungal species that effects humans. Iii) Describe one example of a specific fungal species that effects plants.arrow_forwardFungi play a variety of roles in the ecosystem. Discuss briefly each of the following roles stated below.

- If 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_forwardHealth professionals refer to fungal skin diseases as “tineas” and name them according to the region affected (TABLE 23.1). Fungal skin diseases are persistent, in part because fungi can penetrate deeper layers of skin than can ointments and creams. There are fewer antifungal drugs than antibacterial ones, and antifungals often have more severe side effects. Reflect on the evolutionary relationships among bacteria, fungi, and humans. Why it is harder to fight fungi than bacteria?arrow_forwardCan you please solve number 5 and 6 and show all of the steps and say the correct letterarrow_forward
