Explanation:
Detailed explanation-1: -Cohesion-tension essentially combines the process of capillary action with transpiration, or the evaporation of water from the plant stomata. Transpiration is ultimately the main driver of water movement in xylem.
Detailed explanation-2: -Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants-xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.
Detailed explanation-3: -Explanation: Water and dissolved minerals are absorbed by the root hair of a plant by a process called diffusion.
