NEETBotanyPhotosynthesis in Higher Plants
Which type of plants respond to higher temperatures with a higher rate of photosynthesis?
Options
- AC3 plants
- BC4 plants
- CBoth C3 and C4 plants
- DNeither C3 nor C4 plants
Correct answer
B. C4 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.
