Question

Which plant is most likely to be a C₄ plant?
A) switchgrass
B) clover
C) rose
D) cactus

Accepted Answer

Switchgrass is a warm-season grass that is commonly classified as a C₄ plant. C₄ plants are adapted to hot environments and are more efficient at photosynthesis than C₃ plants, such as clover and rose. Cacti are primarily CAM plants, which use a different type of carbon fixation pathway.
