Transpiration aids in the absorption and upward movement of water and dissolved minerals from roots to leaves, facilitated by the suction effect created during leaf cell evaporation.
How does transpiration contribute to the absorption and movement of water and minerals in plants?

Transpiration plays a crucial role in the absorption and movement of water and minerals in plants. As water evaporates from stomata on leaves, a negative pressure or suction, known as transpirational pull, is created in the xylem vessels. This pull draws water upward from the roots, facilitating its ascent through the plant. This upward flow, termed the transpiration stream, not only transports water but also carries dissolved minerals absorbed by roots from the soil. Transpiration-driven cohesion and adhesion forces enable efficient water movement, facilitating nutrient transport, maintaining turgor pressure, and supporting vital physiological functions in plant cells.
