B. Soil water `to`Root hair cell `to` Pericycle `to`Cortical cell `to` Passage cells `to`Xylem
C. Soil water `to`Root hair cell `to`Cortical cell `to` Passage cells `to` pericycle `to` Xylem
D. Soil water `to`Root hair cell `to` Cortical cell `to` Pericycle `to` Passage cells `to`Xylem

Answer

To determine the correct pathway of water movement in plant roots, we can analyze the options provided step by step:

1. **Understanding Water Movement**: Water enters the plant through the roots, specifically through root hair cells. The movement of water follows a specific pathway from the soil to the xylem.

2. **Analyzing the Options**:
- **Option 1**: Soil → Water → Root Hair Cells → Passage Cells
- This option is incorrect because after root hair cells, the water does not go directly to passage cells.

- **Option 2**: Soil → Water → Root Hair Cells → Pericycle
- This option is also incorrect because the water does not go directly to the pericycle after root hair cells.

- **Option 3**: Soil → Water → Root Hair Cells → Cortical Cells → Passage Cells → Pericycle → Xylem
- This option is correct. Water moves from the soil to the root hair cells, then to the cortical cells, followed by passage cells, pericycle, and finally into the xylem.

- **Option 4**: Soil → Water → Root Hair Cells → Cortical Cells → Pericycle → Passage Cells
- This option is incorrect because the water moves from cortical cells to passage cells, not directly to the pericycle.

3. **Conclusion**: The correct pathway of water movement in plant roots is represented by **Option 3**: Soil → Water → Root Hair Cells → Cortical Cells → Passage Cells → Pericycle → Xylem.
