Question 1
The Jack-O-Lantern mushroom (
Omphalatus illudens
) can easily be confused with prized Chanterelle mushrooms due to their bright orange color, though you should never eat wild mushrooms unless you are
absolutely sure of their identity. Interestingly Jack-O-Lantern mushroom can bioluminescence, possibly attracting nighttime insects to spread their spores.
a. Name the phylum where you would place this organism. (0.5 pt) Basidiomycota
b. Upon what characteristic can you see here to base your decision? (0.5 pt)
I
t's a mushroom, which is a club fungi
c. What toxin does this mushroom contain and what symptoms would you experience letting you know you are not eating Chanterelles? (1 pt)
lludin M and illudin S and you will feel nauseous and vomit.
Question 2
While 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 compactum
b. Why are these compounds important?
Compactim is a cholesterol biosynthesis inhibitor and affects HMG-CoA reductase.
Question 3
When 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 scientific name –written properly) that is used in making brie. In which phylum does it belong? (0.5 pt each)
a. Scientific Name:
P. camemberti
b. Phylum:
Ascomycota
Question 4
Name one ecological role that Fungi play in the environment. Explain why this is important. (1 pt each)
Breaking down other dead organisms into nutrients. This helps recycle the dead organism back into the environment.
Question 5
Although 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:
Are actually a symbiotic relationship between fungi and algae. b. Slime molds:
These also form sporangia. Question 6
a. What is the mechanism that leads to coral bleaching? (1 pt)
Bleaching is caused by algal blooms, which can devastate reefs.
b. Why is coral bleaching such a dire problem? (1 pt)
Many many species of fish, critters, and plants live there. They will have no place to live without corals.
Question 7
All worms are not created equal, nor do they belong to the same phyla.
i. Phyla = Annelida
ii. Phyla = Diplopoda
iii. Phyla = Platyhelminthes
a. Name 2
of the “worms” shown above with their phylum. Be sure to indicate which worm
you are naming in your answer <i, ii, and/or iii>. (0.5 pt each)
ii) millipede iii) flatworm b. Describe how movement differs in the 2 phyla that you named. (2 pts)
One of them has legs, while the other has flaps it uses to glide through the water
Question 8
Crinoids do not look much like the other organisms in their phylum. (0.5 pt each)
a. To what phylum do they belong?
Crinoidea
b. Name one key reason why they are placed in this phylum and not in another group?

THIS IS A MULTIPART QUESTION, PLEASE ANSWER ALL QUESTION
Using the image:
5. Identify whether the organism is a green alga, a diatom, a dinoflagellate, Eubacterium, or a Cyanobacterium. Explain the characteristic(s) that led you to that identification.
6. a. What type of microscopy (brightfield, darkfield, or phase contrast) was to obtain the image? Explain how you can tell.
b. Name a different type of microscopy would be also appropriate to use to visualize the organism in the image. How would the image change if you used that type of microscopy instead?
7. The image was taken using a microscope that has 10X, 40X, and 100X objectives. What is a possible magnification for the ocular lens on this microscope? Explain your response or show calculations.

Paramecium -- Paramecia are quite large, straw-colored, slipper-shaped and move
rapidly, and they are thus very noticeable. If there are Paramecia in your field of view you
probably will recognize them immediately. Often, however, students do have difficulty both
finding a Paramecium, and after they have found one, making it move slowly enough so
they can study it at high magnification. The trick to finding a Paramecium is to scan the
entire slide quickly using the scanning lens. Then, if you do not find one, make a new slide
and search again. Often, Paramecia tend to move to the edges of the coverslip, and even
"escape" the coverslip at its edges. The trick to slowing the Paramecia is to mix a drop of
methyl cellulose with a drop of the cell culture, as…
