Question 1

If atmospheric CO₂ concentrations increase twofold or more,how will plants be affected,disregarding any changes in climate?

Accepted Answer

A) All plants will experience increased rates of photosynthesis. 
B) C₃ plants will have faster growth; C₄ plants will be minimally affected. 
C) C₄ plants will have faster growth; C₃ plants will be minimally affected. 
D) C₃ plants will have faster growth; C₄ plants will have slower growth. 
E) Plant growth will not be affected because atmospheric CO₂ concentrations are never limiting for plant growth.
