The main component of phloem sap is

Answer

**Step-by-Step Solution:**

1. **Understanding Phloem Sap**: Phloem sap is the fluid that flows through the phloem, one of the two types of vascular tissues in plants. It is responsible for the transport of nutrients.

2. **Components of Phloem Sap**: The main components of phloem sap include sugars, amino acids, organic acids, and water. Among these, sucrose is the predominant sugar.

3. **Role of Sucrose**: Sucrose is a disaccharide formed from glucose and fructose. It is the primary form of sugar transported in the phloem, as it is more stable and less reactive than glucose.

4. **Other Components**: In addition to sucrose, phloem sap also contains amino acids (which are building blocks of proteins) and organic acids (which play various roles in metabolism).

5. **Conclusion**: Therefore, the main components of phloem sap are sucrose, amino acids, and organic acids. However, sucrose is often highlighted as the key component due to its abundance and importance in energy transport.

**Final Answer**: The main component of phloem sap is sucrose, along with amino acids and organic acids.
