Yeast is a fungus that reproduces asexually through a process called budding, where a new organism or cell develops from an outgrowth due to cell division.
Yeast is a fungus that reproduces asexually through a process called budding, where a new organism or cell develops from an outgrowth due to cell division.
In your experiment, you assessed yeast reproductive success at three temperatures: 0°C, 35°C, and 99°C.
1. Briefly summarize your results (look at your graph), and the conclusions you can draw from them, in a few sentences.
2. What has led to error (in the statistical sense-think standard error of the mean) in this experiment? In other words, what about the methodology, or the experimental design in general, would you improve in order to collect more accurate data?

How is budding success of yeast impacted by temperature? Does it bud better at cold, moderate, or hot temperatures? Look at your graph to answer these questions. How does 0°C compare with 35°C? How does it compare with 99°C? How does 35°C compare with 99°C? ? Is there a significant difference in budding between temperatures? Remember that a significant difference is not the same as simply a difference. In other words, just because you see a differrence, that does not necessarily mean that there is a significant difference. With that in mind, what conclusions can you draw from your results about yeast budding and temperature?
