Water in plants is transported by or ascent of sap take place through

Options

A. Cambium
B. Phloem
C. Xylem
D. Epidermis

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the mechanism through which water is transported in plants or how the ascent of sap occurs.

2. **Identifying the Options**: The options provided are:
- Cambium
- Phloem
- Xylem
- Epidermis

3. **Analyzing Each Option**:
- **Cambium**: This is a layer of tissue in plants that is involved in secondary growth, but it does not conduct water.
- **Phloem**: This tissue is responsible for the transport of sugars and nutrients, not water.
- **Xylem**: This is the tissue responsible for the conduction of water and minerals from the roots to the rest of the plant. It plays a crucial role in the ascent of sap.
- **Epidermis**: This is the outer layer of cells covering the plant, which does not function in the transport of water.

4. **Conclusion**: Based on the analysis, the correct answer is **Xylem**. It is the primary conducting tissue for water and minerals, facilitating the upward movement of sap from the roots to the leaves.

5. **Additional Information**: Xylem also provides mechanical strength to the plant and is composed of several elements including tracheids, vessels, xylem fibers, and xylem parenchyma.

**Final Answer**: Water in plants is transported by xylem, which facilitates the ascent of sap.
