Recall that C₄plants tend to have higher rates of photosynthesis when compared with C₃ plants (under normal 21% O₂ atmospheric conditions). If photosynthetic rates are higher, why aren't all plants C₄ plants?

Question

Quizplus · Accepted Answer

Although C₄ plants have higher rates of photosynthesis, they also have a higher energy cost for regenerating PEP, which results in a higher demand for resources than C₃ plants. This may make them less suitable for certain environments or conditions.
