Q.Describe the process of cytokinesis that follows karyokinesis in mitosis, and state one way in which cytokinesis in a plant cell differs from cytokinesis in an animal cell.

[!TLDR]

Cytokinesis divides the cytoplasm after karyokinesis; plant cells form a cell plate, animal cells form a cleavage furrow. …

Once karyokinesis (nuclear division) is complete at the end of telophase, cytokinesis divides the cytoplasm itself, distributing the parent cell's cytoplasm and organelles between the two newly formed daughter nuclei to produce two separate daughter cells. In an animal cell, which has only a flexible plasma membrane at its surface, cytokinesis proceeds by the formation of a cleavage furrow -- a constriction of the plasma membrane that deepens progressively around the cell's equator until it pinches the cell fully in two. In a plant cell, the presence of a rigid cell wall outside the plasma membrane makes this inward pinching impossible; instead, a new partition called the cell plate begins forming at the centre of the cell (at the former metaphase plate) and grows outward toward the existing cell wall, eventually dividing the cell into two and later maturing into a new cell wa …

Link the mechanism (furrow vs plate) to the underlying structural cause -- the presence or abse …
