Water is an essential material for the survival of organisms. Water is mainly absorbed by the root system and transported by the catheter in the body where it is needed in the body. Traditional exploration experiments require a preparation of at least one day in advance. By consulting relevant literature not for water transport rapid test validation, using pressure method to improve this experiment, is the teaching material experiment water in plant transport way as the prototype, on the basis of the original experiment of bold design, with a reverse thinking innovation method to rapid validation on the spot of the catheter is the way of water and inorganic salt transport. The stomata of the leaf is the "gateway" for plants to exchange gas and lose water with the outside world. In the experiment, the students
