The Aristidoideae subfamily of grasses inhabits arid regions and respire using the C4 photosynthetic pathway. A related grass, Axonopus compressus, grows in moist, shaded environments and photosynthesizes using the more common C3 photosynthetic pathway. What is a possible explanation for the difference in respiration? @Javk

hey..so I don't know much about this C4 and C3 photosynthetic pathway, but you should check out this link...it's pretty comprehensive ` http://www.plantphysiol.org/content/155/1/56.full `

The C4 pathway allows the plants that live in the drier area to keep their stomata closed more so that they can conserve water.
