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: -Plant cells undergoing cytokinesis (cytoplasmic division) form a cell plate in the center of the phragmoplast. The phragmoplast consists of both cytoskeletal and membranous elements.

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.
