Elephants often considered has a remarkable memory , and now scientists have found that, although the plant has no brain , also learning and memory.
Scientists said that respond to touch , like a fern plant known as the harmless water droplets in the next few weeks still remember this discovery, no longer as a reaction to the drops of water . Their research showed that plant churches learn to survive this experience may also help scientists to a new method to observe flora .
Scientists studied the Mimosa pudica. This plant is to escape a predator damage will be folded inward when touched . The University of Western Australia study shows that this behavior is not just a reflex. Italian experts involved in the study .
The researchers repeated the mimosa to drip with specially designed equipment , analyze short-and long-term memory of this plant in bright light and low light environments. The results showed that water droplets once mimosa not pose a threat to its existence , it will roll up to stop the behavior .
Mimosa can be obtained within a few seconds of learning behavior. And animals, this plant learning speed in low light environments faster. The researchers said: “The most noteworthy is that these plants can still remember a few weeks later learned , it will not lose this ability even after changes in environmental conditions .”
This study shows , mimosa and animal scientists expected with learning and memory , of course, the former is the case in the absence of the brain do. Scientists do not know the real cause of mimosa will learn and remember , but think it may be caused by one of its cells with calcium -based signaling networks caused . It is similar to the memory of animals in some aspects of the process .
Scientists noted that the study has changed the way humans understand the plant and the boundaries between animals and plants from the root , including the definition of biological characteristics of our study is the nervous system. Evolutionary Biology Research Center, University of Western Australia Monica scientists responsible for the study , she said in a recent research paper published in the sounds of plants available to “talk .” This study demonstrated that the plant has the ability ubiquitous in animals .
