Transpiration is the mechanism which powers the “pump” drawing water upwards in a plant from the roots to the leaves.
Water in the leaf evaporates which causes a pressure differential much like sucking on a straw and therefore pulls water from lower down, principally via the xylem cells in the stem(s). The process is not directly linked to photosynthesis and does not require sunlight to operate. An actively photosynthesising plant will usually transpire faster, but that is because sunlight evaporates water faster simply through heat and/or photosynthesis causes a plant to dilate the stomata and allow in more carbon dioxide which secondarily happens to let water vapour escape faster.
