Minerals entering this   tissue must first cross the endodermal Casparian strip, and this tissue has secondary wall thickenings  that can be annular, helical, reticulate, scalariform, or pitted.
Tylosis involves resinous chemicals blocking this tissue type to slow infection. Minerals entering this   tissue must first cross the endodermal Casparian strip, and this tissue has secondary wall thickenings  that can be annular, helical, reticulate, scalariform, or pitted. Both this tissue and ground tissue must   be embedded with lignin to function properly. Transpirational pull allows fluid to move through this  tissue, whose secondary form makes up the heartwood of trees. Tracheids [TRAY- kee-idz] and vessel  elements make up what vascular plant tissue responsible for transporting water, unlike the phloem?
