Phragmoplasts or Phragmosomes, vesicles of GB are the precursors of-

Options

A. Cell plate
B. Chloropalsts
C. Chromoplast
D. Protoplast

Answer

**Step-by-Step Solution:**

1. **Understanding Phragmoplasts and Phragmosomes**:
Phragmoplasts are structures that form during the late stages of cell division in plant cells. They are involved in the formation of the cell plate, which is crucial for separating the two daughter cells after mitosis.

2. **Role of Golgi Bodies**:
Golgi bodies (or Golgi apparatus) are organelles that play a significant role in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles. In the context of cell division, they produce vesicles that contain materials necessary for forming the cell plate.

3. **Formation of the Cell Plate**:
During cytokinesis in plant cells, vesicles derived from the Golgi bodies accumulate at the center of the cell. These vesicles fuse to form the cell plate, which eventually develops into the new cell wall that separates the two daughter cells.

4. **Conclusion**:
Therefore, phragmoplasts or phragmosomes, which are vesicles from the Golgi bodies, are the precursors of the cell plate in plant cells.

**Final Answer**: Phragmoplasts or phragmosomes, vesicles of Golgi bodies, are the precursors of the cell plate.
