Mesarch xylem is present in

Options

A. Ferns
B. Dicots
C. Monocots
D. Bryophyles

Answer

To determine where mesarch xylem is present, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Xylem Types**:
- Xylem is a type of vascular tissue responsible for the transport of water and nutrients in plants.
- There are different types of xylem, including protoxylem, metaxylem, and mesarch xylem.

2. **Identifying Mesarch Xylem**:
- Mesarch xylem is characterized by the presence of both protoxylem and metaxylem in a specific arrangement. It is typically found in certain groups of plants.

3. **Analyzing Plant Groups**:
- The options provided are:
- A) Ferns
- B) Dicots
- C) Monocots
- D) Bryophytes

4. **Evaluating Each Option**:
- **A) Ferns**: Ferns belong to the group of plants known as pteridophytes. They are vascular plants and are known to have mesarch xylem.
- **B) Dicots**: In dicots, the xylem is typically arranged in an endarch or exarch condition, not mesarch.
- **C) Monocots**: Similar to dicots, monocots also do not have mesarch xylem; they usually have an exarch arrangement.
- **D) Bryophytes**: Bryophytes are non-vascular plants and do not have xylem at all, making this option incorrect.

5. **Conclusion**:
- Based on the analysis, the correct answer is that mesarch xylem is present in ferns (option A).

### Final Answer:
**Mesarch xylem is present in ferns.**
