Detailed explanation-1: -The xylem is made up of small vessels that connect the roots and leaves. Xylem transports water, minerals, and nutrients from the soil to all the plant parts.
Detailed explanation-2: -Detailed Solution. The correct answer is Water convection. Xylem is a type of tissue in vascular plants that transports water and some nutrients from the roots to the leaves.
Detailed explanation-3: -Correct answer: Xylem transports water from the roots of a plant to the leaves.
Detailed explanation-4: -The cohesion – tension theory of sap ascent explains how how water is pulled up from the roots to the top of the plant. Evaporation from mesophyll cells in the leaves produces a negative water potential gradient that causes water and minerals to move upwards from the roots through the xylem.
Detailed explanation-5: -Xylem is a complex permanent tissue. It is responsible for the upward conduction of water and minerals in plants. Xylem consists of tracheids, vessels, xylem parenchyma and xylem fibres.
