Q. Choose the correct statement regarding casparian strips I. It surrounds pericycle II. It is made up of legnosuberin III. It limits the pathway available to water solutes, forcing them to enter the symplast
A) I and III
B) I, II and III
C) 1 and II
D) None of these
Explanation
Casparian strips are located in the wall of endodermal cells. These are made up of lignin and suberin. They prevent and block the movement of water and minerals from one side to the other side via cell wall route. So water cannot reach through apoplast but it moves through endodermis by symplastic movement
