Compare the light and dark reactions that occur in plants.

Answer:

The light reactions occur when light is absorbed by the chlorophyll in plants. This light energy is converted to chemical energy in the thylakoids of the chloroplasts in the form of ATP and NADPH. Water splits, producing oxygen gas which is released through the stomata on plant leaves. The dark reactions occur in the stroma of the chloroplasts when carbon dioxide is converted to sugar using energy derived from ATP and NADPH.
