Blog Post Week 2, Plants Can See

This week I found strong evidence that indicates that plants do have senses. In the book, What A Plant Knows, by Daniel Camovitz lies assurance that plants absolutely do see, smell, communicate, feel, and have a sense of proprioception. In a YouTube video of Camovitz speaking to a group of Harvard scholars, he explains how plants are capable of differentiating between light. He explains that plants cannot see pictures, however they can see colors. In a study on plant sight, an iris was exposed to red light and then, to far red light. The red light (resembling sunrise) caused plants to open up and flower, and the far red light (resembling sunset) "inhibited flowering". This shows us that plants can see color. Furthermore, another study done by Charles Darwin showed that they "eye" of a plant is in its leaf. This is the result of an experiment where multiple conditions were tested. In the first trial, the plants tip was cut off, and the plant stopped bending in favor of certain colored lights, it stayed straight up. In the second trail, the tip was covered by an opaque cap, concealing any light from coming within, and again it did not bend in any direction. Finally, (to make sure it wasn't the weight of the cap stopping the plant from bending), a transparent cap was placed on the tip of the plant, and the results showed the plant did in fact bend to one light over another. This is proof that though plants cannot see as humans see, they are capable of sight. How fascinating?! I am amazed at the complexity of the biological threading that plants are composed of that allows them to see, in a way that is so simple, yet extravagant.
