Photosynthate is translocated through

Options

A. Sieve tubes/phloem cells
B. Tracheids
C. Xylem vessels
D. Latex ducts.

Answer

**Step-by-Step Solution:**

1. **Understanding Photosynthate**: Photosynthate refers to the products of photosynthesis, primarily sugars (like glucose), which are produced in the leaves of plants.

2. **Identifying the Transport System**: The transport of photosynthate occurs through specialized structures in plants. The main transport system for sugars is the phloem.

3. **Phloem Structure**: Phloem is composed of different types of cells, including sieve tubes and companion cells. Sieve tubes are the primary conduits for the transport of photosynthates.

4. **Function of Sieve Tubes**: Sieve tubes facilitate the movement of sugars from the source (usually leaves) to various parts of the plant (such as roots, stems, and fruits) where they are needed for growth, storage, or energy.

5. **Direction of Transport**: The transport of photosynthate through phloem is bidirectional, meaning it can move both upwards and downwards within the plant, depending on the needs of different tissues.

6. **Exclusion of Other Options**:
- **Xylem Vessels**: These are responsible for the transport of water and minerals, not sugars.
- **Trachate**: This term refers to a type of water-conducting cell in xylem, not involved in sugar transport.
- **Latex Ducts**: These are involved in the production of latex and do not play a role in the transport of photosynthates.

7. **Conclusion**: Therefore, the correct answer to the question "Photosynthate is translocated through" is **sieve tubes or phloem cells**.
