Tracheids and vessels are related to
(a) Xylem
(b) Phloem
(c) Both
(d) None of these

Options

A. Xylem
B. Phloem
C. Both
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Components**: Tracheids and vessels are both types of cells found in plants. They play a crucial role in the transport of water and minerals.

2. **Identifying the Tissue**: Tracheids and vessels are specifically associated with xylem, which is the tissue responsible for the conduction of water and dissolved minerals from the roots to the rest of the plant.

3. **Differentiating Between Xylem and Phloem**: While xylem is involved in water transport, phloem is responsible for the transport of nutrients and sugars produced by photosynthesis. Therefore, tracheids and vessels do not relate to phloem.

4. **Conclusion**: Since tracheids and vessels are both components of xylem, the correct answer to the question is (a) Xylem.

**Final Answer**: (a) Xylem
