Question

why are casparian strips formed on inner tangential walls of endodermis​

Answer 1

hello!!!

$\huge\mathfrak{Answer}$

The walls of the cells in the middle layer derived from the pericycle became suberized and developed into Casparian strips.

These cells subsequently developed into endodermis-like cells.

The tangential width of endodermis-like cells reduced in sequence from the outer to inner layer.

thanks!!!
