Carbohydrate used in translocation in angiosperms is

Options

A. Ribose
B. Glucose
C. Sucrose
D. Fructose.

Answer

**Step-by-Step Solution:**

1. **Understanding Translocation**: Translocation in angiosperms refers to the movement of nutrients, particularly carbohydrates, from the leaves (where they are produced during photosynthesis) to other parts of the plant.

2. **Identifying the Transport Tissue**: The primary tissue responsible for the transport of carbohydrates in plants is the phloem. This tissue facilitates the movement of sugars and other organic compounds.

3. **Recognizing the Carbohydrates**: The question provides several carbohydrate options: ribose, glucose, sucrose, and fructose. We need to determine which of these is primarily involved in translocation.

4. **Analyzing Each Option**:
- **Ribose**: This is a pentose sugar that is not primarily involved in translocation.
- **Glucose**: While glucose is produced during photosynthesis, it is typically converted into sucrose for transport.
- **Sucrose**: This is a disaccharide that is the main carbohydrate used in the translocation process in angiosperms.
- **Fructose**: This is another simple sugar that is not primarily involved in the translocation process.

5. **Conclusion**: Based on the analysis, sucrose is the carbohydrate that is actively transported from the source (leaves) to the sink (other parts of the plant) via the phloem.

**Final Answer**: The carbohydrate used in translocation in angiosperms is **sucrose**.
