Q: In the process of cell division, the formation of the phragmoplast between the two daughter nuclei occurs during
  • A. S Phase
  • B. Karyokinesis
  • C. G Phase
  • D. Cytokinesis
Correct Answer: Option D - The phragmoplast is a plant cell-specific structure that plays a crucial role in cytokinesis, the process of cytoplasmic division. Cytokinesis is the process during which the cell's cytoplasm divides to form two daughter cells. In plant cells, the phragmoplast forms during cytokinesis, emerging from the remnants of spindle microtubules between the daughter nuclei. It carries vesicles from the Golgi apparatus to the equatorial region of the cell, where they fuse to from the cell plate, eventually leading to the separation of the two new cells.
