when you put a mica plate in the coleoptile E, actually you have cut away the tip of the coleoptile
also, there are some misconceptions in the video...e.g. 'stem' is NOT equal to 'shoot' of the plants.
e.g. the responses of shoot and root to auxins also depend on the concentration of auxins
sorry...i know you have heart to teach...
but try to be more precise (because it is related to the public exam)
