Background Research

The water in a plant pot first enters the plant through the root system. Then it travels up the plants through the stem and into the leaves through the xylem vessels. These vessels which are like capillaries that transports the water into certain parts of the plant.
Water helps sustain the proper temperature inside the bean plant. With out enough water the plants leaves will turn yellow due to the lack of nitrogen in the soil from the water. If the plant receives too much water it will rot the roots and the plant will drown and die. If the plant receives too little water it will wilt and die due to the lack of nutrients. For the plants to survive it will need to have the perfect amount of water.
Based on our research we identified regular water amounts as the control in our experiment and under watering/overwatering as our variable. We hypothesize that if we over water and under water the plants then they will die.
