Vessels and companion cells are respectively present in the xylem and phloem of

Options

A. Gymnosperm
B. Pteridophyte
C. Angiosperm
D. Bryophyta

Answer

**Step-by-Step Text Solution:**

1. **Understanding Xylem and Phloem:**
- Xylem and phloem are two types of vascular tissues in plants. Xylem is primarily responsible for the conduction of water and minerals, while phloem is responsible for the transport of food (mainly carbohydrates).

2. **Components of Xylem:**
- Xylem is a complex permanent tissue composed of several types of cells:
- **Xylem Tracheids:** Long, thin cells that help in water conduction.
- **Xylem Vessels:** Tubular structures that facilitate the efficient transport of water.
- **Xylem Fibers:** Provide structural support.
- **Xylem Parenchyma:** Involved in storage and lateral transport.

3. **Components of Phloem:**
- Phloem is also a complex tissue made up of:
- **Sieve Tubes:** Structures that transport carbohydrates.
- **Companion Cells:** Cells that assist sieve tubes in their function.
- **Phloem Fibers:** Provide support.
- **Phloem Parenchyma:** Involved in storage and transport.

4. **Identifying the Key Features:**
- The question asks about the specific components associated with xylem and phloem.
- The key components are:
- **Vessels** are found in **Xylem**.
- **Companion Cells** are found in **Phloem**.

5. **Conclusion:**
- Therefore, vessels are present in the xylem, and companion cells are present in the phloem of angiosperms.

6. **Final Answer:**
- The correct answer to the question is that vessels and companion cells are respectively present in the xylem and phloem of **Angiosperms**.
