Phloem parenchyma is absent in

Options

A. leaf of monocot
B. Leaf of dicot
C. Stem of Monocot
D. All

Answer

To determine where phloem parenchyma is absent, we need to analyze the options provided:

1. **Understanding Phloem Parenchyma**:
- Phloem parenchyma is a type of parenchyma tissue found in the phloem of vascular plants. Its primary function is to store food and assist in the transport of nutrients.

2. **Analyzing the Options**:
- **Option 1: Leaf of Monocot**:
- Monocot leaves typically have phloem parenchyma present, as they are involved in photosynthesis and nutrient transport.
- **Option 2: Leaf of Dicot**:
- Dicot leaves also contain phloem parenchyma for similar reasons as monocots.
- **Option 3: Stem of Monocot**:
- Monocot stems are generally characterized by the absence of phloem parenchyma. Instead, they have a different arrangement of vascular tissues.
- **Option 4: All of the above**:
- This option implies that phloem parenchyma is absent in all the previous options, which is incorrect based on our analysis.

3. **Conclusion**:
- Based on the analysis, phloem parenchyma is absent in the **stem of monocots**. Thus, the correct answer is **Option 3: Stem of Monocot**.
