A potometer provides a way of both demonstrating and measuring the process of transpiration in plants. Transpiration is the movement of water through a plant - up from the roots right through to the leaves, where it evaporates and is released into the atmosphere via the stomata - tiny pores on the underside of the leaves. As water leaves the plant, more water (if available) is drawn up by the roots. By filling the potometers tubing completely with water, and sealing one end with a leafy shoot cut from a healthy plant, the water loss (in mL) can be measured against the graduated scale.
