Detailed explanation-1: -The two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant.

Detailed explanation-2: -Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.

Detailed explanation-3: -Plant stems have some very special cells called xylem. These cells form long thin tubes that run from the roots up the stems to the leaves. Their job is to carry water upward from the roots to every part of a plant.

Detailed explanation-4: -Infection causes tubes called stromules (blue) to grow from chloroplasts (purple) to the nucleus of a plant cell (yellow) carrying signals that boost immune defenses.

Detailed explanation-5: -The xylem are tiny tubes made of vascular tissue that moves water and minerals up from the ground through the root to the stem.
