Explanation: 

Detailed explanation-1: -Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants-xylem and phloem. 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.

Detailed explanation-2: -Plants have two transport systems-xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.

Detailed explanation-3: -Xylem transports water and dissolved mineral salts from the roots to the rest of the plant.

Detailed explanation-4: -Solution: Osmosis, diffusion, and active transport are the three processes by which plants can absorb water and other minerals of the soil.
