Yeast is unicellular fungi that play an important role in brewing and baking. Take a sample of the yeast and sucrose and make a wet-mount slide.

Fission yeast (Schizosaccharomyces pombe) has become a popular system for studying cell growth and division. It is useful partly because it is easy and inexpensive to grow in the lab, but also because its cells have a regular size and grow only in length, making it very simple to record cell growth.

1. Give a quick description of what you see under the microscopes.

2. What is happening in the beaker with added sucrose? Explain.
