TOUCH ME NOT……(Mimosa Pudica) Yes, it is the name of the plant, it is also called chueemuee is a sensitive plant. The moment you touch it its leaves they almost instantaneously fold together and the leaf stalk droops. This sometimes sets off a chain of reactions, with several leaf stalks falling on top of one another. This touch-induced movement of leaves is known scientifically as thigmonasty, and is thought to be a defensive mechanism against grazers. At night, the leaves will also fold and bend in movements known as nyctonastic movements (reaction to absence of light). Sir Jagdish Chandra Bose, generally known as J C Bose was an Indian scientist who discovered and proved in the world that plants also have life. They consume food and sleep during nights, and wake up early in the mornings. Pain and pleasures are there for plants too. They also have birth, growth and death, as human beings. These are the discoveries of J. C. Bose.
Mimosa Pudica
I remember, during my college i had demonstrated one of the experiments of Dr. J. C Bose. How the plants(Mimosa Pudica) responded to touch. He demonstrated that plants are also sensitive to heat, cold, light, noise and various other external stimuli. Bose contrived a very sophisticated instrument called Crescograph which could record and observe the minute responses because of external stimulants. It was capable of magnifying the motion of plant tissues to about 10,000 times of their actual size, which found many similarities between plants and other living organisms.

Jagdish Chandra Bose was an Indian Physicist who pioneerd the investigation of radio and microwave optics. He took interest in Botany and Zoology too. J C Bose wrote on 1) The Nervous mechanism of plants.2) Response in the living and the non living. These books were world world famous. Plants, scientists say, transmit information about light intensity and quality from leaf to leaf in a very similar way to our own nervous systems. These “electro-chemical signals” are carried by cells that act as “nerves” of the plant .
Florescence Imaginging
Plants can ‘think’ and ‘remember’ Plants are able to “remember” and “react” to information contained in light, according to researchers. The researchers used fluorescence imaging to watch the plants respond In their experiment, the scientists showed that light shone on to one leaf caused the whole plant to respond. The plant] has a specific memory for the light which builds its immunity against pathogens, and it can adjust to varying light conditions.
chemical reactions in leaves not exposed to light
“So the plants perform a sort of biological light computation, using information contained in the light to immunise themselves against diseases that are prevalent during that season.”
