Detailed explanation-1: -leaves with tube-like structures are called vascular plants. Vascular plants include flowering plants, other seed-producing plants, and ferns. Vascular tubes, or veins, carry water and nutrients from the soil to the parts of a plant where they are needed.

Detailed explanation-2: -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. The process by which water evaporates from the leaves and draws more water from the roots is called ‘transpiration’.

Detailed explanation-3: -The xylem transports water and minerals from the roots up the plant stem and into the leaves. In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels. Vessels: Lose their end walls so the xylem forms a continuous, hollow tube.

Detailed explanation-4: -Essentially all of the water used by land plants is absorbed from the soil by roots. A root system consists of a complex network of individual roots that vary in age along their length.
