Photon capture by plant chloroplasts is more efficient than in bacteria because they contain
A)both PS I and PS II.
B)more chlorophyll.
C)LHII,a light harvesting complex.
D)both cyclic and noncyclic photophosphorylation.

Question

Quizplus · Accepted Answer

LHII, or light harvesting complex II, allows for a greater absorption of light energy by the chlorophyll in plant chloroplasts, increasing the efficiency of photon capture. Bacteria may contain a similar complex, but it is typically less developed than that found in plant chloroplasts. PS I and PS II, cyclic and noncyclic photophosphorylation, and chlorophyll concentration may also play a role in photon capture efficiency, but the presence of LHII is the most significant factor.
