Quizplus · Accepted Answer

The flow of water through a plant, from the soil to the leaves, is due to transpiration. Transpiration is the process in which water vapor is released from the pores (stomata) in leaves, creating a negative pressure (tension) that pulls water from the roots up through the plant. This process is powered by the sun's energy and is the main mechanism for water transport in plants. The other choices, such as translocation (movement of nutrients), respiration (energy production), and an internal pump (not present in plants), are not directly involved in the flow of water through a plant.
