Detailed explanation-1: -Which of the following are primarily responsible for cytokinesis in plant cells? Kinetochores.

Detailed explanation-2: -The Phragmoplast Guides Cytokinesis in Higher Plants Rather than a contractile ring dividing the cytoplasm from the outside in, the cytoplasm of the plant cell is partitioned from the inside out by the construction of a new cell wall, called the cell plate, between the two daughter nuclei (Figure 18-37).

Detailed explanation-3: -Plant cytokinesis is centrifugal in nature, the cytoplasmic division starts at the center of the cell and moves towards the cell wall. Animal cytokinesis is centripetal in nature, the cytoplasmic division starts at the edges of the cell at the plasma membrane and moves towards the center.
