If you love gardening, or taking care of plants, losing one can be depressing. Looking at a dying plant may feel a lot sadder after you read this news. Apparently, experts claim that plants can see, smell, hear and even respond!
Researchers at the University of Missouri (MU) studied the behavior of plants, and discovered how it reacts to certain changes in its environment. In the study, experts exposed the plants to caterpillars, which are predators of the chosen specie, Arabidopsis.
They had two groups of plants that were introduced to different environments: the first group where caterpillars were placed, and the second group that was exposed to breeze and was touched with camel hair.
Experts learned that the plants responded differently. The first group of plants reacted to the sound of caterpillars' chewing sound, and produced mustard oil, which is a known insect repellant to defend itself against the predators.
On the other hand, the plants didn't have the same reaction when brushed with camel hair or when exposed to breeze.
"[Plants] are way more clever than we give them credit for," Heidi Appel of the University of Missouri, lead researcher of the study told the Natural News
In other studies, experts have also studied the plant's ability to "see" light. According to experts, because of photoreceptors, plants know where the light is, making them grow towards it.
Plants actually have more photoreceptors than humans and animals. Such as, Arabidopsis possess at least 11 types of photoreceptor, compared to human's four.
These studies prove that though plants lack organs and nervous system, they are more complex than what we know. Plants do excel in other areas. Such as, because they're rooted, plants become more aware of their surroundings.
Now, I miss my mint plant that just passed away. Rest in peace, Walter Minty.
