Answer 1

Casparian strips, that is a band of cell wall material deposited in the radial and transverse walls of the endodermis can be found in monocotyledons and a few eudicots.

Casparian strips are made of mainly lignin and sometimes suberin.

It is a primary developmental stage, in the secondary stage the casparian cells detach from the cytoplasm, creating a secondary cell wall.

Such developments are usually lucid in monocotyledons.
