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: -Vascular plants get their nutrition through the transport of sugars by specialized vessels called phloem. All vascular plants have two types of vessels which make up vascular tissue for the purpose of transport: xylem and phloem.

Detailed explanation-3: -Phloem is a complex permanent tissue that is present in all vascular plants. Phloem consists of various elements-phloem parenchyma, phloem fibers, companion cells, and sieve tubes. The transportation of food in plants through phloem is bidirectional i.e., in both upward and downward directions.

Detailed explanation-4: -Vascular plants contain specialized conducting tissues known as xylem and phloem. They are a type of complex tissue. The arrangement and structure of these tissues differ in different categories of vascular plants like pteridophytes, gymnosperms, monocots and dicots.

Detailed explanation-5: -Xylem is the tissue of vascular plants that transports water and nutrients from the soil to the stems and leaves.
