What determines the temperature optimum for photosynthesis of different plants?

Step-by-step solution

The dark reactions being enzymatic are temperature controlled. Though the light reactions are also temperature sensitive they are affected to a much lesser extent. The C4 plants respond to higher temperatures and show higher rate of photosynthesis while C3 plants have a much lower temperature optimum. The temperature optimum for photosynthesis of different plants also depends on the habitat that they are adapted to . Tropical plants have a higher temperature optimum than the plants adapted to temperate climates.
