Explanation: 

Detailed explanation-1: -Soil is the water source for land plants, and can be an abundant source of water, even if it appears dry. Plant roots absorb water from the soil through root hairs and transport it up to the leaves through the xylem.

Detailed explanation-2: -Plants absorb water from the soil by a process called osmosis – the natural movement of water molecules from an area of high concentration, across a semi-permeable, sieve-like membrane, to an area of low concentration.

Detailed explanation-3: -Water Transport from Roots to Shoots 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.
