The phloem sap is

Options

A. Alkaline
B. acidic
C. low osmotic pressure
D. none of the above

Answer

**Step-by-Step Text Solution:**

1. **Definition of Phloem Sap**: Phloem sap is a fluid found in the phloem tissue of plants. It is responsible for the transport of nutrients, particularly sugars, throughout the plant.

2. **Composition of Phloem Sap**: Phloem sap is a complex mixture that includes both organic and inorganic compounds. The primary components are:
- Sugars (mainly sucrose)
- Amino acids
- Vitamins
- Hormones
- Other organic compounds

3. **pH of Phloem Sap**: The pH of phloem sap is an important characteristic. It is generally considered to be:
- Slightly alkaline or moderately alkaline.
- The typical pH range for phloem sap is between 7.5 and 8.6.

4. **Comparison with Xylem Sap**: It is important to differentiate phloem sap from xylem sap. While phloem sap is alkaline, xylem sap is typically acidic. This distinction is crucial when answering questions related to plant sap.

5. **Conclusion**: Based on the information provided, the correct answer to the question "The phloem sap is" is that it is **alkaline**.

**Final Answer**: The phloem sap is alkaline.
