Cytoplasm division in the end of mitosis

Question

Write the name of the cytoplasm division in the end of mitosis? Also state the differences in this process between plant and animal cells?

Answer 1

Cytoplasm division takes place subsequent to telophase and it is termed as cytokinesis. In animal cells an invagination of the plasma membrane in the direction of cell center emerges in the equator of the parent cell and then the cell is strangulated in that area and classified into two daughter cells. This kind of division is termed as centripetal cytokinesis (from exterior).

In plant cells the cytokinesis is not centripetal as the division occurs from the inside. Membranous sacs packed of pectin concentrate in the interior central area of the cell and propagate to the periphery in the direction of plasma membrane. The pectin-containing sacs fuse themselves and make a central structure termed as phragmoplast. On phragmoplast cellulose deposition takes place and a true cell wall is made to separate the daughter cells. Plant cells therefore existed in centrifugal cytokinesis.

The phragmoplast consists of “failures”, or pores, to allow cytoplasmic communications among the daughter cells. Such openings are termed as plasmodesms
