Explanation: 

Detailed explanation-1: -The ferns, gymnosperms, and flowering plants are all vascular plants. Because they possess vascular tissues, these plants have true stems, leaves, and roots.

Detailed explanation-2: -Like forbs, grasses and trees, ferns are “vascular” plants. They have special tissues that transport fluids and nutrients internally. They also have true root systems, leaves and stems. However, ferns are unlike most plants because they do not produce flowers and seeds.

Detailed explanation-3: -The vascular tissues for which these plants are named are specialized to transport fluid. They consist of long, narrow cells arranged end-to-end, forming tubes. There are two different types of vascular tissues, called xylem and phloem.

Detailed explanation-4: -Vascular plants form xylem-a system of rigid, hollow tubes for water transport from the roots to the rest of plant.

Detailed explanation-5: -The vascular tissue in seedless vascular plants, like ferns, is made up of long, tubelike cells. These cells carry water, minerals, and food to cells throughout the plant.
