Passage cells are found in

Options

A. Endodermis only
B. Exodermis and endodermis
C. Endodermis and pericycle
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Passage Cells**: Passage cells are specialized cells found in certain plant tissues. They play a role in the transport of water and nutrients.

2. **Identifying the Location**: Passage cells are specifically located in the endodermis of plants. The endodermis is the innermost layer of the cortex in roots of terrestrial plants.

3. **Structure of Endodermis**: The endodermis consists of living cells that are tightly packed together. This compact arrangement is crucial for its function.

4. **Function of Passage Cells**: Within the endodermis, some cells are designated as passage cells. These cells facilitate the movement of water and nutrients from the soil into the vascular system of the plant.

5. **Conclusion**: Based on the above points, we conclude that passage cells are found in the endodermis of terrestrial plants.

**Final Answer**: Passage cells are found in the endodermis.
