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: -animal cells form a cleavage furrow and plant cells form a cell plate in cytokinesis. Both the cleavage furrow and the cell plate facilitate the cytoplasm of the dividing cell to split and form two separate daughter cells.

Detailed explanation-4: -In plant cells, a cleavage furrow is not possible because of the rigid cell walls surrounding the plasma membrane. A new cell wall must form between the daughter cells.
