The specific function of light energy in the process of photosynthesis is to
(a) reduce carbon dioxide.
(b) synthesis glucose
(c) activate chlorophyll.
(d) split water molecule.
(c) activate chlorophyll.
Light is also used to signal the activation of the Calvin-Benson cycle (which is inhibited in the dark to conserve energy in the chloroplast) and to regulate many other developmental processes that affect photosynthesis. The synthesis of chlorophyll itself involves a light-catalyzed reaction. In motile plants (such as swimming green algae), light is also used for navigation.
