Final answer:
The newly formed cell plate during plant cytokinesis is coated by membranes of Golgi vesicles which come together to create the new plasma membrane that divides the two daughter cells, and eventually leads to the formation of a new cell wall.
Step-by-step explanation:
During cytokinesis in plant cells, after the nucleus has divided, a new cell wall must be created to separate the two daughter cells. This process involves the accumulation of enzymes, structural proteins, and glucose within the Golgi apparatus during interphase. As the cell progresses to telophase, the Golgi breaks into vesicles which are transported along microtubules to form a structure known as a phragmoplast at the metaphase plate. These Golgi vesicles then coalesce at the center and grow outward toward the existing cell walls, resulting in a structure called a cell plate. Following the formation of the cell plate, the membranes of these vesicles come together to create a new plasma membrane that separates the two cells. Finally, the accumulated enzymes use glucose to construct a new cell wall between the daughter cells, using the Golgi membranes as part of the plasma membrane on either side of this new cell wall.
In plant cells, the newly formed cell plate is coated by Golgi vesicles. These vesicles coalesce at the former metaphase plate, forming a structure called a phragmoplast. The vesicles fuse and coalesce from the center toward the cell walls, ultimately forming a cell plate. The membranes of the vesicles then fuse to form a plasma membrane that divides the cell in two.
