PLANTS - Algae can take energy from other plants

Flowers need water and light to grow. Even children learn that plants use sunlight to gather energy from earth and water. Biologists have made an astounding discovery that one plant has another way of doing this. They have confirmed for the first time that a plant not only engages in photosynthesis, but also has an alternative source of energy: it can draw it from other plants. This finding could also have a major impact on the future of bioenergy.
