Abstract
When an animal is hungry or thirsty, it goes searching for something to eat or drink. If the sun feels too hot, the animal moves to the shade, and if the wind or the precipitation is too fierce, the animal seeks shelter. Most plants cannot do any of these things; they have to stay where they have germinated. A plant must collect its energy and building materials on the spot, and cope with the hardships that may be encountered there. It cannot flee its enemies but has to defend itself. The plant must use physiology where the animal can resort to behaviour, and this is one reason why plant physiology is such a fascinating subject.
