Detailed explanation-1: -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-2: -Vascular plants get water through their root system, and it is conducted up through the plant within vascular tissue called xylem. Vascular plants have true roots, stems and leaves, as well as a specialized vascular system made of vessels called xylem and phloem.

Detailed explanation-3: -After traveling from the roots to stems through the xylem, water enters leaves via petiole (i.e., the leaf stalk) xylem that branches off from that in the stem.

Detailed explanation-4: -The bulk of water uptake by most plants is via the roots. That said, high humidity does decrease the rate at which water is lost from the plant, and so will decrease the uptake of water from the soil.

Detailed explanation-5: -The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. The phloem and xylem are the main tissues responsible for this movement.
