Detailed explanation-1: -In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast. A cell plate formed by the fusion of the vesicles of the phragmoplast grows from the center toward the cell walls, and the membranes of the vesicles fuse to form a plasma membrane that divides the cell in two.
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: -The formation of the cell plate takes place during the mitotic phase.
Detailed explanation-4: -Cytokinesis (/ˌsaɪtoʊkɪˈniːsɪs/) is the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis.
Detailed explanation-5: -The cell membrane does not pinch. The cell membrane is pinched off into two daughter cells. No such event in plant cells. A contractile ring is formed in the middle by the actin and myosin filaments that pull the cleavage furrow towards the centre.
