The walls of sieve tubes develop into sieve plates together getting associated with …………

Options

A. Chiasmata
B. Plasmodesmata
C. Tractile fibers
D. Ultra-cellular strands

Answer

To solve the question "The walls of sieve tubes develop into sieve plates together getting associated with …………", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Sieve Tubes**:
- Sieve tubes are specialized structures in the phloem of plants that are responsible for the transport of nutrients, particularly sugars.

2. **Identifying Sieve Plates**:
- Sieve plates are the porous end walls between sieve tube elements that facilitate the flow of sap.

3. **Exploring the Options**:
- The question provides four options:
- A) GASMETA
- B) PLASMODESMETA
- C) TRACTILE FIBERS
- D) ULTRACELLULAR STRANDS

4. **Analyzing Each Option**:
- **GASMETA**: This term does not relate to plant cell structures.
- **PLASMODESMETA**: These are channels that connect the cytoplasm of adjacent plant cells, allowing for communication and transport of substances.
- **TRACTILE FIBERS**: These are associated with cell division and are not related to sieve tubes.
- **ULTRACELLULAR STRANDS**: This term is not commonly used in plant biology and does not relate to sieve tubes.

5. **Choosing the Correct Answer**:
- Based on the analysis, the correct answer is **PLASMODESMETA**. These structures are crucial for the association between sieve tube members and companion cells, allowing for the transport of nutrients and signaling.

### Final Answer:
The walls of sieve tubes develop into sieve plates together getting associated with **PLASMODESMETA**.
