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: -In the vessels the transverse walls between the cells break down and this results in continuous, lignin-lined tubes than run from the root to the growing tip of the shoot.

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: -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-5: -As we just learned, roots have a vascular cylinder, which in simple terms is a cylinder in the middle of the roots that has xylem and phloem. These two tissues are found in all plant organs: roots, stems, leaves, and reproductive organs.
