Plants Possess Nervous System

Green Memory

A team led by Stanislaw Karpinski from Warsaw University of Life Sciences in Poland has found that plants as a whole possess a nervous system which is prominently similar to that of humans. The team found that plants remember and react to changes around them just like humans.

Researchers in order to demonstrate these characteristics used fluorescence imaging to gauge response of plants. For this, they exposed a single leaf of a plant to light and found that the entire plant reacted to it. The reaction was in the form of light-induced chemical reactions which lingered on even after the plant was placed in the dark. It demonstrated to scientists that plants remembered this encrypted information by using specific cells known as ‘bundle sheath cell’.

The research established the fact that plants have a nervous system which the research team suggests is used by them to stimulate protective chemical reactions and immunise themselves against pathogens.

The most wonderful and precious element of universe is the human life which can only be guided by the right knowledge and right attitude. So, here is an ocean of knowledge, both in English and Hindi encompassing every detail and each facet of human life which ‘one must know’ in order to grow and attain the summits of success. A team of around 200 dedicated members is working ceaselessly to turn such a colossal dream into reality. We are confident that this portal will help bring change in people across the world.
