How does cytokinesis in plant cells differ from that in animal cells?
Cytokinesis is different in an animal and a plant cell. In animal cells a cleavage furrow appears at the beginning of telophase. This furrow or constriction becomes progressively deeper as the spindle breaks down. Eventually, the in-growing constrictions join and separate two daughter cells. This division of cytoplasm is called cytokinesis. When nuclear division takes place without cytoplasmic division, it results in the formation of syncytium, which is a condition where a large number of nuclei are present in a single cell.In plants, there is a formation of cell plate between the two daughter nuclei. This grows from the middle towards the periphery and finally joins the cell wall. The cell plate represents the middle lamella between the walls of two adjacent cells. During cell division, cell organelles like mitochondria, plastids, golgi complex, lysosomes and the cytoplasmic matrix are distributed into the two daughter cells. Of these, mitochondria and plastids reproduce themselves, but details of the fate of other organelles are not yet known.
