Who discovered plants were alive, how, n when preferably?

The scientist who first discovered that plants have life was Sir Jagadish Chandra Bose an Indian scientist.

Sir Jagadish Chandra Bose,[1] CSI,[2] CIE,[3] FRS[4] (Bengali: জগদীশ চন্দ্র বসু Jôgodish Chôndro Boshu; 30 November 1858 – 23 November 1937) was a Bengali polymath, physicist, biologist, botanist, archaeologist, as well as an early writer of science fiction.[5] He pioneered the investigation of radio and microwave optics, made very significant contributions to plant science, and laid the foundations of experimental science in the Indian subcontinent.[6] IEEE named him one of the fathers of radio science.[7] He is also considered the father of Bengali science fiction. He was the first person from the Indian subcontinent to receive a US patent, in 1904. He also invented the crescograph.

Bose subsequently made a number of pioneering discoveries in plant physiology. He used his own invention, the crescograph, to measure plant response to various stimuli, and thereby scientifically proved parallelism between animal and plant tissues. Although Bose filed for a patent for one of his inventions due to peer pressure, his reluctance to any form of patenting was well known. To facilitate his research, he constructed automatic recorders capable of registering extremely slight movements; these instruments produced some striking results, such as Bose’s demonstration of an apparent power of feeling in plants, exemplified by the quivering of injured plants. His books include Response in the Living and Non-Living (1902) and The Nervous Mechanism of Plants (1926).

Adam and Eve, we have always known that plants have life.
