This will be an example of the scientific process which underlies all of the information presented in Bio 111. This patch has a red center and a white edge. Your task is to figure out as much as you can about why the middle is red and the edge is white. Instead, your objective is to find some piece of the answer that the community of scientists in your lab section can agree on. Click here for more pictures of the yeast experiment.
Yeast is a single-celled organism, a type of fungus.
The particular species of yeast we will be using is Saccharomyces cerevisiae , the species of yeast used to bake bread. When you buy yeast for baking at the supermarket, it is dried, but still living, cells of Saccharomyces cerevisiae . This is called exponential growth. Budding occurs roughly every 2 hours. That means in 24 hours, one cell would give rise to roughly 4000 decendants.
