Phloem does not have parenchyma in

Options

A. Monocot stem
B. Dicot stem
C. Dicot root
D. Dicot leaf

Answer

To solve the question, "Phloem does not have parenchyma in," we need to analyze the components of phloem in different types of plants.

### Step-by-Step Solution:

1. **Understanding Phloem Structure**:
- Phloem is a complex permanent tissue in plants responsible for the transport of nutrients, particularly food (sugars) produced through photosynthesis. It consists of several components: sieve tube elements, companion cells, phloem parenchyma, and phloem fibers.

2. **Identifying Components of Phloem**:
- **Sieve Tube Elements**: These are the main conducting elements of phloem.
- **Companion Cells**: These assist in the functioning of sieve tubes by maintaining the pressure gradient.
- **Phloem Parenchyma**: These cells are primarily involved in the storage of food.
- **Phloem Fibers**: These provide structural support.

3. **Analyzing the Options**:
- The question provides four options: monocot stem, dicot stem, dicot root, and dicot leaf. We need to determine where phloem lacks parenchyma.

4. **Monocots vs. Dicots**:
- In **monocots**, the phloem does not contain parenchyma cells. This is a distinguishing feature of monocotyledonous plants.
- In **dicots**, phloem parenchyma is present in the stem, root, and leaf.

5. **Conclusion**:
- Based on the analysis, the correct answer is that phloem does not have parenchyma in the **monocot stem**.

### Final Answer:
Phloem does not have parenchyma in **monocot stem**.
