Professor Dave Explains's video: Plant Responses to the Environment: Tropisms and Defenses

We've already learned a little bit about plant hormones, but let's dig a little deeper so that we can really examine the different ways that plants can respond to stimuli. These are called tropisms, and they can be positive or negative, depending on whether plants grow or move towards or away from things like light and water.
