Detailed explanation-1: -Photosynthetic capacity, air temperature, daily PAR and photoperiod all increased in the early summer and then declined over the late summer and autumn (Figure 1).
Detailed explanation-2: -The rate of photosynthesis does not increase with higher temperatures for all plants. Plants which grow in colder climates have an optimum rate of photosynthesis at low temperatures.
Detailed explanation-3: -The higher temperature increases the rate of reaction of enzymes involved in photosynthesis.
Detailed explanation-4: -As temperature increases the number of collisions increases, therefore the rate of photosynthesis increases. However, at high temperatures, enzymes are denatured and this will decrease the rate of photosynthesis.
