1. In the lab, we observed how pillbugs move towards the moist chamber and how the planarium move away from the toothpick touch. Explain how the two types of responses are similar, and how are they different.

2. Why the pillbug choice chamber exercise was done with 10 pillbugs per attempt instead of a single pillbug.

3. In the pillbug choice chamber exercise, the first condition we tested was placing two identical pieces of dry filter paper into the chamber, one on each side. Why was this step necessary? In what way can the result of this set up be used to help us analyze other data?

4. Compare and contrast the movement of a mimosa plant's touch response to the plant root's gravitropic response. How are they similar? How are they different?
