Physical Stress - Temperature

We are most familiar with the plants and other organisms that live at temperatures close to the temperature range in which we are adapted to live i.e., 15° to 45°C. However, we know that there is life below 0°C in the arctic and above 90°C in the sulphur springs. In the subtropical zones, plants face stress -when they get exposed to freezing temperatures during the winters while in the deserts of the tropics the native plants withstand over 55°C during summer. High, temperature can be inhibitory for photosynthesis.
