NEET BIOLOGY

Detailed explanation-1: -Caspar strips are a water-impermeable layer of water present in the endothelium. It fills the space between cells of the root endodermis. Casparian strips are present in the roots of both monocotyledonous and dicotyledonous plants.

Detailed explanation-2: -The central vascular structures of dicot roots are encircled by the ground tissue, which is primarily made up of parenchyma cells. The dicot root’s innermost cortical layer contains Casparian strips.

Detailed explanation-3: -Casparian strip-A band of suberin, an impermeable substance, found in the endodermal cell walls of plant roots; it was named after R. Caspary.

Detailed explanation-4: -Casparian strips are a cellular feature found in the roots of all higher plants. They are ring-like, hydrophobic cell wall impregnations. These impregnations occur in the endodermis, an inner cell layer that surrounds the central vascular strand of roots (Figure 1).
