Detailed explanation-1: -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-2: -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-3: -They consist of long, narrow cells arranged end-to-end, forming tubes. There are two different types of vascular tissues, called xylem and phloem. Both are shown in Figure below. Xylem is vascular tissue that transports water and dissolved minerals from roots to stems and leaves.

Detailed explanation-4: -Plants have two transport systems-xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.

Detailed explanation-5: -Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants). Scientific names for the group include Tracheophyta, Tracheobionta and Equisetopsida sensu lato.
