Dermal tissues, ground tissues and vascular tissues of the plants are produced by.

Options

A. Lateral merisem, Cork cambium and vascular cambium
B. Intercalary meristem and lateral meristem
C. Apical meristem
D. Fascicular cambium and interfascicular cambium

Answer

To determine which type of meristem produces dermal tissues, ground tissues, and vascular tissues in plants, we can analyze the options provided and the role of different types of meristems.

### Step-by-Step Solution:

1. **Understanding Meristems**:
- Meristems are regions in plants where cells are actively dividing. They are responsible for the growth of the plant.

2. **Types of Meristems**:
- There are three main types of meristems:
- **Apical Meristem**: Located at the tips of roots and shoots, responsible for primary growth (lengthening).
- **Lateral Meristem**: Involved in secondary growth (thickening), includes vascular cambium and cork cambium.
- **Intercalary Meristem**: Found at the base of leaves or internodes, allows for regrowth after cutting.

3. **Identifying Tissues Produced**:
- **Dermal Tissues**: These are the outer protective layer of the plant, produced by the apical meristem.
- **Ground Tissues**: These tissues make up the bulk of the plant body and are also produced by the apical meristem.
- **Vascular Tissues**: These include xylem and phloem, which are essential for transport within the plant, and are produced by the apical meristem.

4. **Analyzing the Options**:
- **Option A**: Lateral meristem, cork cambium, and vascular cambium - primarily involved in secondary growth.
- **Option B**: Intercalary meristem and lateral meristem - not primarily responsible for dermal and ground tissues.
- **Option C**: Apical meristem - responsible for producing dermal, ground, and vascular tissues.
- **Option D**: Fascicular cambium and interfascicular cambium - related to vascular tissue but not dermal or ground tissues.

5. **Conclusion**:
- The correct answer is **Option C: Apical meristem**, as it is responsible for producing dermal tissues, ground tissues, and vascular tissues in the primary plant body.

### Final Answer:
**The dermal tissues, ground tissues, and vascular tissues of the plants are produced by the apical meristem.**
