TheC4plants show higher rate of photosynthesis ina)Optimum temperatureb)High temperaturec)Absence of temperatured)Low temperatureCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

C4 planets show higher rate of photosynthesis in higher temperatures because there is no energy loss in  photorespiration in these plants, i.e.at high temperature they show full efficiency of production.

Answer

The criteria C4 plants to produce better yield to have every factors at a higher level and therefore temperature is one of the factor of photosynthesis,it is required in higher amount

Answer

As C3 plants have special feature i.e kranz anatomy and circular bundle sheath
but c4 plants has some sort of factors on which their rate of photosynthesis is high
High temperature is one of the suitable factor on which C4 plants show very high rate of photosynthesis
hence option B is correct

Answer

Answer

Higher rate of photosynthesis in C4 plants at high temperatures
C4 plants have a specialized mechanism for carbon fixation that allows them to photosynthesize more efficiently in hot and dry conditions compared to C3 plants. This adaptation gives them an advantage in environments with high temperatures.

Reasons for higher photosynthesis rate in C4 plants at high temperatures:
1. Optimal functioning of the C4 pathway: The C4 pathway involves a series of biochemical reactions that occur in different cell types within the leaf. At high temperatures, the enzymes involved in the C4 pathway can function optimally, leading to increased efficiency in carbon fixation and photosynthesis.
2. Reduced photorespiration: High temperatures can increase the rate of photorespiration in C3 plants, which can reduce the efficiency of photosynthesis. In contrast, C4 plants have a mechanism that minimizes photorespiration, allowing them to maintain a higher rate of photosynthesis at high temperatures.
3. Efficient water use: C4 plants have a higher water use efficiency compared to C3 plants, which is beneficial in hot and dry conditions. This efficiency allows C4 plants to continue photosynthesizing at high temperatures without experiencing as much water loss.
4. Adaptation to hot climates: C4 plants are typically found in tropical and subtropical regions with high temperatures. Their ability to photosynthesize efficiently at high temperatures is an adaptation that allows them to thrive in these environments.
In conclusion, C4 plants show a higher rate of photosynthesis at high temperatures due to their specialized carbon fixation pathway, reduced photorespiration, efficient water use, and adaptation to hot climates.
