False.
Light-dependent reactions need light, so most photosynthetic activity is daytime—but some plants (CAM species like cacti and many succulents) open stomata and fix CO2 at night into organic acids, and the dark (Calvin) reactions can continue for a time using stored energy. Thus not all carbon-fixation-related steps occur only in daylight.
