Detailed explanation-1: -The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

Detailed explanation-2: -Final answer: Roots are not involved in the process of transpiration.

Detailed explanation-3: -Transpiration (water transport) involves three processes: absorption at the roots, capillary action in the xylem, and evaporation at the leaves. Roots acquire dissolved minerals in a four-step process: •Active transport into the root hairs, which moves minerals against their concentration gradient.
