One of the many characteristic that separates species from the Animalia kingdom from species from the Plantae kingdom is the concept of of vision. Vision is most commonly described as the ability to see. I always thought that to see is to use your eyes and interpret what is around you. This thought is very subjective because human only know it as common occurrence within animals. The vast majority of animals have the ability to see. A small rodent sees a predatory bird flying around. This will prompt the rodent to hide in its habitat. The idea is that rodent detected the presence of the bird flying using its vision. This is a stimulus-response mechanism where the bird acts like the stimulus, and the rodent reponses by running away. This is a common trend in many ecosystems that directly involve animals. The question is do plants follow this idea. Plants do not have eyes, but eyes in the notion of being the organ that detects the multiple electromagnetic waves, which we know as the rainbow colors, in light which then converts into impulses that neurons that the brain can interpret. The eye works very similar to how a television projects all the different colors on the screen. The only difference is the resolution of eyes to the resolution of common cameras. Vision works as a stimulus-response mechanism which plants definitely follow. Many flowers follow the sun as it moves from the east to the west. The question is why? The answer is that plants have a version of vision, but not the stereotypical vision that most humans believe to be. The question was first investigated hundreds of years ago with the first experiment conducted by Darwin. Darwin is the father of genetics, and his work revolutionized the field of biology. His experiments showed that plants bends toward the direction of light. He showed this by placing plants in a very dark room with a light in a corner. The plant’s tip bent in the direction of the light. Now, the question what part of the plant was responsible for this. Darwin followed through with more experiments that resulted in knowing that the tip is responsible with directions. Four plants were used during the experiment with one of them being the control. The control did not have alteration done to the plant. The second plant’s tip was removed. The third and fourth had a covering which was dark and clear, respectively. The control and clear covering bending toward the light, while the other two had no changes. The results led to more discovery. Plants can tell whether it’s night or day. This works like the internal clockwork that humans have. The exposure of light tells the plant about sunlight. Even more experiments were done with some results. Plants bend in the direction of blue lights, and red light tells plants the length of the night. This discovery helps farmers control when plants can flower or delay when to flower.
