Xylem and phloem
In Class 9 Science, this topic from “Tissues in Action” explains how vascular tissues transport materials through plants. Students learn that xylem carries water and dissolved minerals from the roots to the stems and leaves, while phloem distributes food made during photosynthesis to growing and storage regions. The topic connects the structure of xylem vessels, tracheids, sieve tubes, and companion cells with their functions, helping students compare water transport and food translocation and understand how these tissues support plant growth.
