Stele consits of

Options

A. Phloem
B. Xylem
C. Pericylcle
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Stele":**
- The term "stele" refers to the central part of the root or stem in vascular plants. It is a crucial component that houses the vascular tissues.

2. **Components of the Stele:**
- The stele consists of several types of tissues that are essential for the plant's transport system. The primary components include:
- **Xylem:** This tissue is responsible for the transport of water and minerals from the roots to the rest of the plant.
- **Phloem:** This tissue transports the products of photosynthesis (mainly sugars) from the leaves to other parts of the plant.
- **Pericycle:** This is a layer of cells that surrounds the vascular tissues and can give rise to lateral roots.

3. **Origin of the Stele:**
- The tissues that make up the stele are derived from a specific type of meristematic tissue known as procambium. This tissue differentiates into the vascular tissues (xylem and phloem) and the pericycle.

4. **Conclusion:**
- Since the stele includes xylem, phloem, and pericycle, the correct answer to the question "Stele consists of" is "all of the above."

**Final Answer:**
- The stele consists of phloem, xylem, and pericycle, thus the answer is **all of the above.**
