Tissues Class 9 Notes Right here We have now supplied abstract and revision notes for Class 9 Science Chapter 6. Xylem may be outlined as a posh tissue that’s composed of 4 fundamental forms of cell tracheids trachea and xylem fibre and xylem parenchyma stays in shut affiliation with phloem and has specialised features like conduction of water and solutes and mechanical power.
Higher and decrease portion of cell. Xylem fibres present power to the tracheids and vessels. They’re the vascular tissues that transport substances all through the plant.
Moreover this transportation occurs in an upwards method from the roots to the opposite components of the crops. Easy complicated and secretory or particular. Xylem is the water conducting factor transportation of water which additionally offers mechanical power to the plant.
