Description: Temperature is prominent among the major ecological variables that determine the natural distribution of plants. Habitats occupied by higher plants show dramatic differences in the prevailing temperature during the period of active growth, ranging from near freezing in certain arctic and alpine environments to over 50°C in the hottest deserts. Moreover, in many habitats the same plant individual is subjected to a very wide seasonal variation in temperature regime and even diurnal temperature fluctuation can be considerable.
Like almost all other growth processes, photosynthesis is strongly affected by temperature. In most plants, changes in photosynthetic rate in response to temperature are reversible over a considerable range (commonly 10° to 35°C), but exposure to temperatures below or above this range may cause irreversible injury to the photosynthetic system. Thus, in addition to the effect of temperature on photosynthesis arising from the intrinsic temperature dependence of the process in the range over which the functional integrity of the photosynthetic apparatus remains intact, extreme temperatures can drastically inhibit photosynthesis by disrupting the integrity of the system.
