Casparian bands are found in

Options

A. Endodermis
B. Epidermis
C. Pericycle
D. Phloem

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where Casparian bands are found in a plant. The options provided are endodermis, epidermis, pericycle, and phloem.

2. **Identifying the Correct Structure**: Among the options, the endodermis is known to have Casparian bands. The endodermis is a single layer of cells that acts as a boundary between the cortex and the vascular tissues of the plant.

3. **Describing the Endodermis**: The endodermis consists of barrel-shaped cells that lack intercellular spaces. This structure is crucial for regulating the flow of water and nutrients into the vascular system.

4. **Understanding Casparian Bands**: Casparian bands are thickened regions found in the walls of the endodermal cells. These bands are made up of materials such as lignin, suberin, or cutin, which help in preventing the passive flow of substances into the vascular system.

5. **Conclusion**: Since Casparian bands are specifically located in the endodermis, the correct answer to the question is the endodermis.

**Final Answer**: Casparian bands are found in the endodermis.
