The presence of only PS I, not PS II, in the bundle-sheathcells of C4 plants has an effect on O2 concentration. Whatis that effect, and how might that benefit the plant?
It is the term referring to the characteristic leaf structure of C4 plants that enables them to outperform C3 plants in an environment that has high O2 concentration and/or temperature. Unlike C3 and CAM plants, C4 plants, such as corn and sugarcane, have leaves with vascular bundles that are surrounded by a chloroplast-rich vascular bundle sheath, which is further surrounded by the spongy mesophyll.
If a C3 plant and a C4 plant are placed in separate sealedcontainers and provided with adequate light and water, bothwill survive. If both plants are placed in a single sealed container, the C3 plant will die. Explain.

A researcher tested CCCP on the green alga Hydrodictyon africanum. Results showed that CO2CO2 fixation was severely inhibited, whereas O2O2 release and production of NADPH were only mildly affected. What is the MOST likely explanation of the results for the inhibition of carbon fixation? A. CCCP disrupts the synthesis of ATP at the mitochondrial membrane. B.
