The temperature has an important influence on the growth and the survival of the plants, too cold or too hot, the temperatures can contribute in the death of plants.
Each plant has its “comfort zone” of temperature, it depends on the region of origin of the plant. The higher the temperature (while remaining in this comfort zone), the more the plant practices photosynthesis. Indeed the production of chlorophyll is influenced by the temperature.
Other events can also destabilize the plant, such as a sudden change in temperature.
