Water enters a plant at the root system and moves upwards through specialized tissue called xylem. Xylem carries water all the way to the plant’s extremities, where some escapes into the air through minute openings in the outer surface. This loss of moisture is called transpiration. In hot conditions, large trees can lose huge volumes

Batteries harness energy from the motion of electrons. How do we get electrons going? Chemistry! Most batteries use a simple oxidation-reduction (or redox) reaction to get electric charges moving. In a redox reaction, one material gives electrons to another. We call the donor the anode and the recipient the cathode. Strategic separation of the anode
