Identify the tissue system from among the following:

Options

A. parenchyma
B. xylem
C. laticifers
D. epidermis

Explanation

To identify the tissue system from the given options, we need to analyze each option based on their characteristics and classification in plant anatomy.

### Step-by-Step Solution:

1. **Understand the Options**: We have four options to consider:
- Parenchyma
- Xylem
- Lactifers
- Epidermis

2. **Analyze Parenchyma**:
- Parenchyma is a type of simple tissue composed of parenchyma cells.
- These cells are usually involved in storage, photosynthesis, and tissue repair.
- Since parenchyma is classified as a simple tissue, it does not form a tissue system.
- **Conclusion**: Parenchyma is not the answer.

3. **Analyze Xylem**:
- Xylem is a type of vascular tissue responsible for the transport of water and minerals from the roots to the rest of the plant.
- It is composed of various cell types including xylem vessels, tracheids, and sclerenchyma.
- Since xylem is a complex tissue made up of multiple cell types, it is indeed part of a tissue system.
- **Conclusion**: Xylem is a tissue system.

4. **Analyze Lactifers**:
- Lactifers are specialized elongated cells that secrete latex or other secondary metabolites.
- They are considered simple tissues and do not form a tissue system.
- **Conclusion**: Lactifers are not the answer.

5. **Analyze Epidermis**:
- Epidermis is the outermost layer of cells covering the plant.
- It is made up of a single layer of cells and serves protective functions.
- While it is a tissue, it is classified as a simple tissue rather than a tissue system.
- **Conclusion**: Epidermis is not the answer.

6. **Final Conclusion**:
- Among the options provided, the only one that qualifies as a tissue system is **Xylem**.

### Final Answer:
The correct answer is **Xylem**.
