Xylem || Complex Permanent Tissue || Tracheids, Vessels, Xylem Parenchyma & Xylem Sclerenchyma

This video is part of the chapter Anatomy of Flowering Plants and is useful for the students of Class 11, Class 12, B.Sc. 2nd year and for the students preparing for competitive exams.
Xylem is the Water Conducting Tissue of the Plants and is a dead Tissue.
