Chemical analysis of phloem shows the presence of

Options

A. More amount of carbohydrates
B. Organic nitrogenous compounds
C. Minerals
D. Both (a) and (b)

Explanation

### Step-by-Step Solution:

1. **Understanding Phloem**: Phloem is a type of vascular tissue in plants responsible for the transport of nutrients, particularly food materials (mainly carbohydrates) produced during photosynthesis.

2. **Chemical Composition of Phloem**: When conducting a chemical analysis of phloem, we focus on the substances that are present in the phloem sap. The main components found in phloem include carbohydrates, organic nitrogenous compounds, and minerals.

3. **Key Components**:
- **Carbohydrates**: The primary carbohydrate found in phloem is sucrose, which is a product of photosynthesis and is transported from the leaves (source) to other parts of the plant (sink).
- **Organic Nitrogenous Compounds**: These are essential for various metabolic processes and are also transported through the phloem.
- **Minerals**: Essential minerals are also transported in the phloem, although they are primarily absorbed by the roots and transported through xylem.

4. **Conclusion**: Therefore, the chemical analysis of phloem shows the presence of carbohydrates, organic nitrogenous compounds, and minerals. The correct answer to the question is that phloem contains both carbohydrates and organic nitrogenous compounds.

5. **Final Answer**: The chemical analysis of phloem shows the presence of carbohydrates and organic nitrogenous compounds (both A and B).
