Detailed explanation-1: -Plants have a pipe like vessels made of special cells known as vascular tissues which transport minerals, water, and food synthesized by leaves. These vascular tissues are xylem and phloem. Xylem transports water and minerals from roots to leaves through the stems and branches.

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: -The ferns, gymnosperms, and flowering plants are all vascular plants. Because they possess vascular tissues, these plants have true stems, leaves, and roots.
