The correct answer is phragmoplast Explanation & Key Takeaways: • During cell division, the formation of a new cell wall is followed by the accumulation of phragmoplast. • The phragmoplast is a plant cell structure that forms during late cytokinesis. • It serves as a scaffold for cell plate assembly and subsequent formation of a new cell wall separating the two daughter cells. • The phragmoplast consists of microtubules, actin filaments, and vesicles derived from the Golgi apparatus. Related Concepts: • The phragmoplast is initially formed from the remnants of the mitotic spindle. • Vesicles containing cell wall materials are transported along the microtubules to the center of the cell where they coalesce to form the cell plate. • As the cell plate matures, it expands outward to fuse with the existing cell membrane, completing the separation of the two daughter cells. • This process is crucial for plant growth and development, ensuring that each new cell is properly encased in a cell wall.
