Write short note on Xylem <!--td {border: 1px solid #cccccc;}br {mso-data-placement:same-cell;}--> [Textbook Question No.5b Pg no. 208]

Answer 1

Xylem is a complex permanent tissue as it contains more than one type of cells. Different types of cells present in xylem are:

• Tracheids: It is a non- living cell, having tapering ends.
• Vessels: It is a non-living cell having a tubular structure.

Both tracheids and vessels are responsible for conduction of water and minerals vertically.

• Xylem fibres: It is a non-living cell and provides support.
• Xylem parenchyma: It is a living cell and stores food and helps in sideways conduction of water.

Conduction occurs only in an upward direction.
