Detailed explanation-1: -In plants, water and minerals are transported through xylem cells from soil to the leaves. The xylem cells of roots, stems and leaves are interconnected to form a conducting channel that reaches all parts of the plant body. The root cells take ions from the soil.

Detailed explanation-2: -The xylem is a tissue which transports water and minerals from the roots up the plant stem and into the leaves. Xylem consists of dead cells.

Detailed explanation-3: -Transportation of water takes place through tracheids and vessels, the dead cells of xylem.

Detailed explanation-4: -The xylem tissue carries water and mineral ions from the soil up to the stem and the leaves. The mineral ions and water only travels in one direction. Xylem cells are dead. The phloem tissue transports sugars made from the leaves to the rest of the plant.

Detailed explanation-5: -Water from the soil enters the root hairs by moving along a water potential gradient and into the xylem through either the apoplast or symplast pathway. It is carried upward through the xylem by transpiration, and then passed into the leaves along another water potential gradient.
