Main water-conducting element of xylem in homoxylous plants is
(a) Trachea
(b) Vessel
(c) Tracheid
(d) Xylem parenchyma

A

vessels

B

C

transfusion tissue

D

tracheids

Text Solution

Verified by Experts

The correct Answer is:
d
The tracheids are elongated , angular dead cells with hard lignified wide lumen and narrow end walls. The walls of tracheids possess different types of thickenings and the unthickened areas of its wall allow the rapid movements of water from one tracheid to another . Tracheids are the characteristic cell types of xylem tissues in gymnosperms and pteridoohytes, where they are the chief elements of water conduction.
