Correct Answer: Transpiration
Solution : The correct option is Transpiration.
Excess water collected by plants is mostly released or expelled by a process known as transpiration. Water is pulled up from the roots of plants, passes through the plant's vascular system (xylem), and finally evaporates into the atmosphere through tiny apertures in the leaves. The evaporation of water from the leaves causes a negative pressure or tension in the xylem, which aids in the removal of additional water from the roots. Transpiration is essential for water and nutrient transfer throughout the plant.
