Mineral nutrients absorbed by roots, move to leaves through

Options

A. xylem
B. phloem
C. sleve tube
D. companion cell

Explanation

**Step-by-Step Solution:**

1. **Understanding Mineral Nutrients**: Mineral nutrients are inorganic substances that plants absorb from the soil through their roots. These nutrients are essential for various physiological functions in plants.

2. **Direction of Transport**: The transport of mineral nutrients is unidirectional, meaning they move in one direction, specifically from the roots to the leaves.

3. **Identifying the Transport Tissue**: In plants, there are two main types of vascular tissues involved in the transport of nutrients:
- **Xylem**: This tissue is responsible for the transport of water and dissolved mineral nutrients from the roots to the leaves. It operates in a unidirectional manner.
- **Phloem**: This tissue transports organic nutrients (like sugars produced during photosynthesis) and operates in a bidirectional manner, meaning it can transport substances both upwards and downwards.

4. **Evaluating the Options**:
- **Option A: Xylem** - Correct, as it transports mineral nutrients from roots to leaves.
- **Option B: Phloem** - Incorrect, as it primarily transports organic nutrients.
- **Option C: Sieve Tubes** - Incorrect, as they are part of the phloem and transport organic nutrients.
- **Option D: Companion Cells** - Incorrect, as they support sieve tubes but do not transport nutrients themselves.

5. **Conclusion**: Based on the analysis, the correct answer to the question is **Xylem**, as it is the tissue responsible for transporting mineral nutrients absorbed by the roots to the leaves.

**Final Answer**: The mineral nutrients absorbed by roots move to leaves through **Xylem**.
