Detailed explanation-1: -While the circulatory system is responsible for this task in humans, plants have structures called xylem and phloem that move resources like water and sugars from one place to another. Typically, xylem and phloem are grouped together in vascular bundles, that allow water to be exchanged between the two as needed.
Detailed explanation-2: -The vascular bundles are arranged near the edge of the stem, with the phloem on the outside and the xylem on the inside.
Detailed explanation-3: -Plant vascular tissues provide physical strength to plant bodies and transport water, nutrients and other substances required for growth and defense. They interconnect all the plant body parts by their conductive function, from the root tip to the various organs in the shoot.
Detailed explanation-4: -Vascular bundles play important roles in transporting nutrients, growth signals, amino acids, and proteins between aerial and underground tissues.
