Minerals absorbed by roots move to the leaf through

Options

A. Xylem
B. Phleom
C. Sieve tubes
D. Companion Cells

Answer

To answer the question "Minerals absorbed by roots move to the leaf through," we will analyze each option provided and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Role of Xylem**:
- Xylem is a type of vascular tissue in plants responsible for the transport of water and dissolved minerals from the roots to the leaves and other parts of the plant.
- When roots absorb water from the soil, they also take in minerals dissolved in that water.

**Hint**: Remember that xylem is primarily involved in transporting water and minerals upward in the plant.

2. **Evaluating the Role of Phloem**:
- Phloem is another type of vascular tissue, but its main function is to transport organic nutrients, particularly sugars produced during photosynthesis, from the leaves to other parts of the plant.
- It does not primarily transport minerals from the roots to the leaves.

**Hint**: Phloem is associated with the distribution of food (sugars), not minerals.

3. **Considering Sieve Tubes**:
- Sieve tubes are part of the phloem and are responsible for the transport of nutrients. However, they do not play a role in transporting minerals from the roots.
- They work alongside companion cells to facilitate the movement of organic compounds.

**Hint**: Sieve tubes are involved in nutrient transport but are not responsible for mineral movement.

4. **Understanding Companion Cells**:
- Companion cells assist sieve tubes in the phloem by helping to transport sugars and amino acids. They do not transport minerals from the roots to the leaves.
- Their function is more about supporting the sieve tubes in nutrient transport.

**Hint**: Companion cells support nutrient transport but are not involved in mineral transport.

5. **Conclusion**:
- Based on the analysis of each option, the correct answer is that minerals absorbed by the roots move to the leaves through **xylem**.

### Final Answer:
Minerals absorbed by roots move to the leaf through **xylem**.
