A researcher exposes two genetically identical plants to different light intensities. Plant A receives high intensity monochromatic red light, while Plant B receives low intensity polychromatic light. Assuming all other factors are optimal, which statement is MOST likely true regarding the quantum yield of photosystem II (ΦPSII)?
Plant A will likely have a higher ΦPSII than Plant B.
Plant B will likely have a higher ΦPSII than Plant A.
The ΦPSII will be approximately equal in both plants.
The ΦPSII will be zero in both plants due to the different light conditions.
