Detailed explanation-1: -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-2: -Cytokinesis is the physical process that finally splits the parent cell into two identical daughter cells. During cytokinesis, the cell membrane pinches in at the cell equator, forming a cleft called the cleavage furrow.
Detailed explanation-3: -During telophase and cytokinesis, vesicles collect along the center of the cell and coalesce (or come together), forming the cell plate. As vesicles fuse, the cell plate grows, building a cell wall. The cell plate will continue to grow until it eventually attaches to the plasma membrane.
Detailed explanation-4: -Cytokinesis begins in anaphase and ends in telophase, reaching completion as the next interphase begins. The first visible change of cytokinesis in an animal cell is the sudden appearance of a pucker, or cleavage furrow, on the cell surface.
