Experiment 1: Symmetry in Common Objects
Symmetry can be seen in everyday objects similar to that of the symmetry seen
in organisms.
Images of Common Lab Equipment
1. Review the objects listed below (many of these can also be found in your
lab kit).
2. Indicate the type of symmetry each item displays next to the image in the
Post-Lab Questions section.
Hint: It is helpful to draw lines of symmetry over the objects and observe
objects from different angles.
3. For each item, explain why you chose the type of symmetry you did.

Experiment 2: Observing Ascomycota (Yeast)
Yeast is a commercially important member of the Fungi Kingdom. It leavens
bread and produces beer and wine. Yeast is unique because it is unicellular and
reproduces by mitosis and budding.
Yeast Digital Slide Images
Peziza Digital Slide Images
1. View the digital slide image of yeast (Figure 11). Locate the budding cells
and label what you see in the space below. Using the slide as a reference
draw a budding yeast cell and include important structures (ascus
ascospore) on your picture.
2. View the digital slide image of Peziza (Figure 12). Identify the asocarp
asci, ascospores, and sterile hyphae.

Post-Lab Questions
1. Compare yeast to the Peziza slide. Identify at least one difference, and
one similarity.
2. How many ascospores are in each ascus of the yeast?
