Final answer:
The cell plate formed during cytokinesis assists in the division of plant cells by creating a new cell wall between the daughter cells.
Step-by-step explanation:
The part of the plant cell that helps during cell division, specifically during the final stage known as cytokinesis, is the cell plate. In plant cells, unlike animal cells, a new cell wall must be constructed between the newly-formed daughter cells. During cell division, microtubules guide the formation of this cell wall, and cellulose is laid down by enzymes to form the primary cell wall. This process begins during telophase, where Golgi vesicles containing enzymes and structural proteins aggregate to form a phragmoplast at the metaphase plate. These vesicles then coalesce, starting from the center and moving outward, forming the cell plate, which eventually merges with the existing cell walls to create two distinct daughter cells.
In plant cells, the cell plate helps the cell during cell division. The cell plate is formed by vesicles from the Golgi apparatus, which fuse together to build the new cell wall between the daughter cells. Enzymes use glucose accumulated between the membrane layers to construct the cell wall.
