“Pre-Lab QuesCons”
1. What is a model organism, and why is Saccharomyces cerevisiae so o<en used as one?
Model organisms is used for research and analysis. Sacchgromyces are used because
of it small and fast growth rate, and is easy and safe to work with.
2. Research and discuss the properBes of mold that make them someBmes beneficial to humans,
and someBmes potenBally harmful.
can be beneficial to humans in the way that it can be used in medications. It is harmful to
humans because it can be aspergillum and inhalation can lead to serious problems since
mold produces toxins.
3. ParasiBc helminths are a major cause of disease in undeveloped countries around the world.
Discuss the role that microbiologists can and have played in helping to reduce the number of
infecBons caused by parasiBc helminths.
microbiologist can help prevent transmission with better hygiene, hand washing , getting
your vaccines and staying up to date and drinking water.

Post-Lab Ques0ons
1. Which condiBon produced the most mold growth? The least? The fastest? The slowest?
Most mold growth, was dark sugar and dark water. The least was dark vinegar and dark
lemon and the bright vinegar and bright lemon.
2. What was the purpose of examining three pieces of bread and three pieces of apple in each
treatment?
to see where the mold grew more.
3. Based on your results, what condiBons are most favorable for mold growth on bread? On apple?
with water and neutral the ph
4. Would these condiBons apply to all fungal growth?
no
5. Did you noBce a difference in mold growth on the bread vs the apple? If so, what do you think
might account for this difference?
apple , I think the apple has less preservatives than bread
