Q: Answer-Given below are two statements Statement I: C₃ plants are more efficient than C₄ plants in terms o...

C plants are actually more efficient than C plants in terms of carbon dioxide fixation. C plants have adapted a more efficient carbon fixation pathway that allows them to minimize photorespiration and increase photosynthetic efficiency, particularly in high-temperature and high-light conditions. C plant loses half as much as water as a C plant as C plants need not to open their stomata for long to take in carbon dioxide due to high efficiency of the C pathway and this reduces water loss due to transpiration. The water loss per gram of biomass produced with C cycle is high 450-950. However, the water loss per gram of biomass produced with C cycle is low 250-350

plants are more efficient than C₄ plants in terms of carbon dioxide fixation Statement II: C₄ plants are less water efficient and consume more amount of water then C₃ plans for same amount of CO₂ fixed. In light of the above statements, choose the correct answer from the options given below

A Both Statement I and Statement II are true

B Both Statement I and Statement II are false

C Statement I is true but Statement II is false

D Statement I is false but Statement II is true
