Food is translocated in phloem as

Options

A. Starch
B. Sorbito
C. Sucrose
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Phloem Function**:
- Phloem is a type of vascular tissue in plants responsible for the transport of food, primarily in the form of sugars.

2. **Identifying Source and Sink**:
- The source is the part of the plant where food (sugars) is produced, typically the leaves (photosynthetic organs).
- The sink is the part of the plant where food is utilized or stored, such as roots or fruits (non-photosynthetic organs).

3. **Conversion of Sugars**:
- In plants, glucose (a simple sugar) produced during photosynthesis is converted into sucrose (a disaccharide) for transport.
- This conversion is important because sucrose is a non-reducing sugar, meaning it does not readily react with other substances, making it more stable for transport.

4. **Transport Process**:
- The transport of sucrose occurs from the source (leaves) to the sink (roots) through the phloem.
- The sucrose enters companion cells and then into the phloem vessels for long-distance transport.

5. **Final Conclusion**:
- Food is translocated in phloem primarily as sucrose, which is the correct answer to the question.

**Final Answer**: Food is translocated in phloem as sucrose.
