what is stimulus? Explain me?

CHANGES I N OUR ENVIRONMENT WHICH MAKE US RESPOND IS CALLED STIMULUS.

FOR EG1) WHEN WE GET ANELECTRIC SHOCK WE IMMEDIATELY MOVE OUR HAND AWAY FROM IT

2) IN PLANTS IF THE PLANTS ARE COVERED AND VERY LESS SUNLIGHT IS COMING JUST BEFORE AMPLE LIGHT IS COMMING THEN PLANTS WILL BEND TOWARD IT

3) SOME PLANTS RESPOND TO STIMULIBY TOUCH SUCH AS MIMOSA PUDICA { MY SPELLING MAY BE WRONG }

4) ALSO MANY FLOWERS LIKE CHINA ROSE OPEN IN THE MORNING AND CLOSE IN THE EVENING.

THESE ARE EVERYDAY EXAMPLES OF STIMULI.NOT ONLY THIS THERE ARE MANY MORE .

ALSO THE EXAMPLE GIVEN BY SUCHITA WAS ALSO A GOOD EXAMPLE.

IF HELPFUL THEN THUMSUP PLZ...........
