Detailed explanation-1: -Cytokinesis occurs by a special mechanism in higher-plant cells-in which the cytoplasm is partitioned by the construction of a new cell wall, the cell plate, inside the cell. The position of the cell plate is determined by the position of a preprophase band of microtubules and actin filaments.

Detailed explanation-2: -Cytokinesis in plant cells involves the formation and insertion of a new cell wall that separates daughter nuclei after mitosis. The deposition of the new wall is regulated by a structure called the phragmoplast which contains microtubules, actin filaments and membranes.

Detailed explanation-3: -What makes a cell plate? Vesicles filled with enzymes, structural proteins, and glucose molecules collect along the center of the cell during telophase and cytokinesis forming the cell plate. As vesicles fuse, the cell plate grows, building a cell wall.
