The phragmoplast is organised:-

Options

A. At the beginning of anaphase
B. At the end of anaphase
C. At the beginning of telophase
D. At the end of telophase

Answer

To determine when the phragmoplast is organized, we need to understand its role and the phases of cell division. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Phragmoplast**: The phragmoplast is a plant cell-specific structure that forms during cell division, particularly during cytokinesis. It serves as a scaffold for the assembly of the cell plate, which will eventually develop into a new cell wall between the two daughter cells.

2. **Identifying the Phases of Cell Division**: The main phases of cell division include prophase, metaphase, anaphase, telophase, and cytokinesis. We need to focus on the latter phases where cytokinesis occurs.

3. **Analyzing the Options**:
- **Option 1: Beginning of Anaphase**: This is incorrect because the phragmoplast does not form during anaphase; this phase is primarily about the separation of chromatids.
- **Option 2: End of Anaphase**: This is also incorrect. Although chromatids are moving towards the poles, the phragmoplast is not yet organized.
- **Option 3: Beginning of Telophase**: This option is incorrect as well. At the beginning of telophase, the chromatids are already separated, but the phragmoplast has not yet formed.
- **Option 4: End of Telophase**: This is the correct answer. At the end of telophase, the cell is preparing for cytokinesis, and the phragmoplast is organized to facilitate the formation of the cell plate.

4. **Conclusion**: The phragmoplast is organized at the end of telophase, which corresponds to the late stages of cytokinesis.

### Final Answer:
The phragmoplast is organized at the **end of telophase** (Option 4).
