Caption: An aquarium tank containing sprigs of pondweed (Elodea sp.) with a digital oxygen sensor and portable data collecting device. Oxygen bubbles on the side of the tank are the result of photosynthesis. The computer interfaced sensor is monitoring changes in dissolved oxygen over time as a result of the plant's photosynthetic activity. Elodea is a genus of closely related aquatic plants native to North America. They are important producers in pond ecosystems, and are used widely in home aquariums and school experiments. Some species have been introduced to Europe, Africa, Australia and other areas where they are considered a noxious, invasive species.
