Plants use two different strategies; transpirational pull and root pressure for the transportation of water and minerals during day and night.

Root Pressure is the positive pressure created by the movement of water from the roots to the soil for upward movement of water. The effect of root pressure in transport of water is more important at night.

Transpiration pull is the pull of water as a result of tension created by transpiration in the aerial parts of the plant. It is the major driving force of water movement upwards in a plant during the day.
