Be sure to refer to the images on the lab website when answering these questions.Question 1 (refer to website image)Question 2Question 3Question 4Question 5Question 6Question 7 (refer to website images)Question 8 (refer to website image)Question 9Question 10 (refer to website image)Fungal and Invertebrate Webquest Answer sheetFall 2020Name: Kemany Ullah Lab Section #: 006CBe sure to refer to the images on the lab website when answering these questions. Question 1 (refer to website image)Below is an image of the Death Angel or Destroying Angel mushroom (Amanita ocreata). While it looks similar to some other edible wild mushrooms, it is quite deadly to eat.a. Name the phylum where you would place this organism. (0.5 pt) Basidiomycetesb. Upon what characteristic can you see here to base your decision? (0.5 pt) It’s a fungus that reproduces sexuallyc. What toxin does this mushroom contain and how does this toxin ultimately kill those who eat it? (1 pt) It contains amatoxin, which inhibits RNA polymerase II and III.Question 2While the first antibiotic was made from the fungus Penicillium, some species of Penicillium have been found to produce cholesterol lowering compounds. Name 1 of the species of Penicillium (give the full scientific name –written properly) that produces such compounds. (0.5 pt each)a. Scientific name: Penicillium citrinumb. Why are these compounds important? These compounds are important because they can help solve issues for millions of AmericansQuestion 3When making brie or camembert cheese, the initial cheese curd is packed into molds, washed, salted, and then inoculated with a fungus. The fungus will impart flavor as it further digests the young cheese and forms the rind of the cheese. Name one species of fungi (give the full scientificname –written properly) that is used in making brie. In which phylum does it belong? (0.5 pt each)a. Scientific Name: penicillium camembertib. Phylum: sac fungiQuestion 4Name one ecological role that Fungi play in the environment. Explain why this is important. (1 pt each) Fungi play a major role as decomposers and recyclers, making it possible for membersFungal and Invertebrate Webquest Answer sheetFall 2020Name: Kemany Ullah Lab Section #: 006Cof other kingdoms to be supplied with nutrients. The food web would be incomplete without them.Question 5Although lichens and slime molds are not true fungi, we often study them along with fungal groups. What characteristics of these groups align them with Fungi? (1 pt each)a. Lichens: Lichens are classified within fungi based on the way they look as they are mostly ascomycetesb. Slime molds: (1 pt) both are eukaryotic organisms, show a heterotrophic mode of nutrition, form sporangiaQuestion 6a. What is the mechanism that leads to coral bleaching? (1 pt)When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white.b. Why is coral bleaching such a dire problem? (1 pt)Bleaching leaves corals vulnerable to disease, stunts their growth, affects their reproduction, and can impact other species that depend on the coral communities.Question 7 (refer to website images)All worms are not created equal, nor do they belong to the same phyla.a. Name 2 of the “worms” shown above with their phylum. Be sure to indicate which worm you are naming in your answer. (1 pt) 3rd pic: Platyhelminthes, 1st pic: Nematodab. Describe how movement differs in the 2 phyla that you labeled. (2 pts) One moves by ciliary activity and the other by dorso ventral bending Question 8 (refer to website image)Crinoids do not look much like the other organisms in their phylum. (0.5 pt each)Fungal and Invertebrate Webquest Answer sheetFall 2020Name: Kemany Ullah Lab Section #: 006Ca. To what phylum do they belong? Echinodermatab. Name one key reason why they are placed in this phylum and not in another group? Because of how much they are related to starfish and sea urchinsQuestion 9Your textbook divides the phylum Arthropoda into 4 major Classes: Chelicerata, Crustasea, Hexapoda and Myriapoda. (1 pt each)a. Which Class is mostly aquatic, was represented on the Arthropod table in the Fungi/Invert lab,and are abundant in many plankton samples, such as what you will see in the Aquatics Communities Lab?Crustaceab. Give one example from this Class of Arthropoda. Crabsc. Describe one major characteristic that distinguishes this Class from the other three Classes? Living mostly underwaterQuestion 10 (refer to website image)The organism pictured below belongs to the phylum Mollusca. (1 pt each)a. To which class of Mollusca does this animal belong? chitonsb. Without any obvious limbs, how does the pictured organism move? crawlingc. If this organism did not have 8 shell-like plates on its back/dorsal side, but instead may lack an exoskeleton and move using muscular arms and/or a siphon for jet propulsion, in which Class of Mollusc would you now place it?
