(a) Epidermis (b) Endodermis
(c) Pericycle (d) Phloem

Answer 1

Explanation:

    (b) The casparian bands occur Endodermis layer.

1. The Casparian band is framed from the affidavit of suberin and lignin in the outspread and transverse cell dividers. This happens at or approach the finish of the development zone where the protoxylem vessels develop and get conductive.  
2. The dialect suberized thickenings present on the outspread dividers and digressive dividers of the endodermal cells are called Casparian groups.  
3. Casparian groups are available in full grown phellem cells in the two stems and underlying foundations of P. hortorum.
4. It is suggested that Casparian groups act to impede water misfortune and pathogen passage through the essential cell dividers of the phellem cells, therefore adding to the primary elements of the periderm .
5. The endodermal layer in a plant, quite often in the root, controls the water and different substances that get into the plant.
6. The endodermis is a solitary layer of cells that outskirts the cortex of a root.
