1. Based on the passage, do you think photosynthesis can take place without the presence of light? 2. What could be your idea about the relation of light dependent reaction and light-independent reaction?
1.At night, or in the absence of light, photosynthesis in plants stops, and respiration is the dominant process. The plant uses energy from the glucose it produced for growth and other metabolic processes.
(in short YES)
2.In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.
