Under what conditions are C4 plants superior to C3 ?
Answer - C4 plants are considered to be superior to C3 plants. This is because of the following reasons.
- C4 plats indicate a high optimum temperature value, whereas C3 plants indicate the lesser value of optimum temperature ranges. As a result, photosynthesis in C4 plants can take place in the presence of high-temperature ranges, whereas C3 plants cannot initiate photosynthesis under such conditions.
- At low carbon dioxide ranges, C4 plants can carry out the process of photosynthesis effectively. At the same time, C3 plants fail to do so. This is because the presence of carbon dioxide is a limiting factor in the case of C3 plants.
- High oxygen levels in the environment affect C3 plants because Kranz anatomy is absent. This is not in case of C4 plants. Kranz
anatomy in C4 plants ensures that photorespiration do not occur.
