NEET BIOLOGY

Detailed explanation-1: -Moderate heat stress causes a reversible reduction of photosynthesis; increased heat stress causes irreversible damage to the photosynthetic apparatus, resulting in greater inhibition of plant growth [7].

Detailed explanation-2: -Temperature has an impact on the rate of photosynthesis. The rate of photosynthesis increases as the temperature rises. During photosynthesis, a temperature of more than 40 °C slows down the process.

Detailed explanation-3: -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.

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.
