Phragmoplast is precursor of

Options

A. Leucoplast
B. Chloroplast
C. Chromoplast
D. Cell plate

Answer

To answer the question "Phragmoplast is a precursor of," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Phragmoplast**:
- Phragmoplast is a structure that forms during the later stages of cell division, specifically during cytokinesis in plant cells. It is composed of microtubules and microfilaments.

2. **Formation of Phragmoplast**:
- The phragmoplast is formed by the fusion of microtubules, microfilaments, and the endoplasmic reticulum. This fusion creates a cylindrical structure that plays a crucial role in cell division.

3. **Role of Phragmoplast**:
- The primary function of the phragmoplast is to guide the formation of the cell plate, which eventually leads to the separation of two daughter cells during cell division.

4. **Identifying the Precursor**:
- When vesicles accumulate at the center of the phragmoplast, they fuse to form the cell plate. Therefore, the phragmoplast acts as a precursor to the cell plate.

5. **Choosing the Correct Option**:
- Given the options:
- 1. Leukoclast
- 2. Chloroplast
- 3. Chromoclast
- 4. Cell Pellet
- The correct answer is option number 4, "Cell Pellet," as the phragmoplast is indeed a precursor to the cell plate, which is also referred to as the cell pellet.

### Final Answer:
Phragmoplast is a precursor of **Cell Pellet** (Option 4).
