Pre-lab Questions
1. What is a model organism, and why is Saccharomyces cerevisiae so
often used as one? A model organism is a species that is studied
extensively to comprehend certain biological phenomena with the
insights gained from the research applicable to other organisms. For
, several reasons, baker's yeast, also known as Saccharomyces
cerevisiae is widely used as a model organism for example, it shares
many cellular functions and features with higher eukaryotes. Also, it
has a short and simple cell cycle, facilitating rapid experimentation
and observations. Moreover, its genetics are well understood, with
many tools and resources available for genetic manipulation.
Furthermore, S. cerevisiae is unicellular, yet exhibits complex cellular
processes, making it a valuable system for studying fundamental
biological principles.
2. Research and discuss the properties of mold that make them
sometimes beneficial to humans, and sometimes potentially harmful.
A beneficial property of molds includes their role in the
decomposition of organic matter, aiding in the recycling of nutrients
in ecosystems. Furthermore, certain molds are used in the production
of food and beverages, for example in the fermentation of cheese.
They can be harmful when they produce mycotoxins, which are toxic
substances that contaminate food and pose health hazard risks to
animals and humans.
3. The lab guide discussed “acellular” organisms. What characteristics
classify them as acellular?
Would you consider these living organisms?
Acecullar organisms are organisms that lack a cellular structure. They
are typically comprised of genetic material either DNA or RNA
surrounded by a protein coat. I would not classify them as living
organisms as they do not carry out essential life processess
independently.
