Dr. Dudley talked about the parts of the plant, and the adaptations and defenses some plants have.
For example, the mimosa plant (or sensitive plant) curls up on contact to protect itself. We tried this for ourselves by touching mimosa leaves and watching them react to our touch.
We also got to trigger venus flytraps and watch them close.
The McMaster Greenhouse was a great place to explore, and I was really glad to have the opportunity to visit!
