Detailed explanation-1: -The rate of photosynthesis increases as the temperature rises. During photosynthesis, a temperature of more than 40 °C slows down the process. Because it is an enzyme-controlled process, this is the case. It occurs as a result of enzymes being involved in temperature-sensitive chemical processes.
Detailed explanation-2: -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.
Detailed explanation-3: -At low temperatures, the rate of photosynthesis is limited by the number of collisions between enzymes and substrate. As temperature increases the number of collisions increases, therefore the rate of photosynthesis increases.
Detailed explanation-4: -The rate of photosynthesis is highest when the temperature is between 10-20 degrees C (50-68 degrees F). This is because, like other reactions occurring in living organisms, plants rely on enzymes to help keep the reaction going and increase the rate of the reaction.
Detailed explanation-5: -Photosynthesis is an enzyme mediated process. We know that enzymes work in optimum range of temperature. When the temperature goes beyond this range, an enzyme cannot work. Due to this, the rate of photosynthesis decreases at higher temperature.
