Question

Casparian strips occur in

• A. Pericycle
• B. Cortex
• C. Endodermis
• D. Epidermis

Answer 1

The correct option is C

Endodermis

The correct option is C

Explanation of the correct option:

1. The Casparian strip is found in the root endodermis.
2. These are ring-like cell wall modifications in the endodermis.
3. They form barriers between vascular tissue and outer ground tissues for selective absorption of water and nutrients.

Explanation of the incorrect option:

Option A:

1. The pericycle is the primary tissue of the root parts of a plant.
2. It plays an important role in the formation of lateral roots and vascular and cork cambium in the rapid division.

Option B:

1. Cortex is the plant tissue located in between the epidermis and the vascular tissues of roots and stems.
2. It contains stored materials like latex, and renin. essential oils.

Option D:

1. The epidermis is the outer surface layer covering stems, leaves, roots, fruits, and seeds.
2. The epidermis is a waxy layer and acts as a protective part against injury and infection.

Final answer: Casparian Strips occur in Endodermis.
