Transpiration facilitates the movement of water and dissolved minerals from the roots to the leaves. As water is drawn upward through the xylem, it carries minerals dissolved in the soil solution, ensuring their transport to all parts of the plant for growth and metabolic functions.
How does transpiration impact the uptake of minerals and nutrients by plants?

Transpiration plays a crucial role in the uptake of minerals and nutrients by plants through the process of mass flow. As water is transpired from the leaf stomata, it creates a negative pressure in the xylem, resulting in the upward movement of water from the roots. This mass flow also carries dissolved minerals and nutrients absorbed by the roots from the soil solution. The transpiration stream helps transport essential elements, such as ions and nutrients, to various parts of the plant, supporting growth and metabolic processes. It is a key mechanism for the efficient uptake and distribution of vital nutrients in plants.
