why does root pressure in transport of water is more important in night

Expert Answer
During the night time, the process of transpiration is next to impossible or negligible. Also, the evaporation is also very less at the night. This means that the pressure on the roots is a major force that will allow the movement of water in a plant during the night hours.
Root pressure is more essential at night because there is no sunlight and transpiration does not occur and hence water cannot reach to leaves without tranpirational pull. Hence, at night plants totally depend on root pressure to absorb water from soil.
