Cytokinesis illustration Ciliate undergoing cytokinesis, with the cleavage furrow being clearly visible.. Cytokinesis (/ ˌ s aɪ t oʊ k ɪ ˈ n iː s ɪ s /) is the part of the cell division process and part of mitosis during which the cytoplasm of a single eukaryotic cell divides into two daughter cells.
After cytokinesis is complete, one of the two daughter cells inherits a remnant known as the midbody ring. [ 8 ] Activation of the cell-cycle kinase (e.g. Rho-kinases ) during telophase initiates constriction of the actomyosin ring by creating a groove that migrates in an inward motion.
In plant cells, Golgi vesicle secretions form a cell plate or septum on the equatorial plane of the cell wall by the action of microtubules of the phragmoplast. [2] The cleavage furrow in animal cells and the phragmoplast in plant cells are complex structures made up of microtubules and microfilaments that aide in the final separation of the ...
The cell plate will transform into the new cell wall once cytokinesis is complete. The phragmoplast is a plant cell specific structure that forms during late cytokinesis . It serves as a scaffold for cell plate assembly and subsequent formation of a new cell wall separating the two daughter cells.
While cytokinin action in vascular plants is described as pleiotropic, this class of plant hormones specifically induces the transition from apical growth to growth via a three-faced apical cell in moss protonema. This bud induction can be pinpointed to differentiation of a specific single cell, and thus is a very specific effect of cytokinin. [18]
What is clearly visible in plants cells which exhibit cytoplasmic streaming is the motion of the chloroplasts moving with the cytoplasmic flow. This motion results from fluid being entrained by moving motor molecules of the plant cell. [8] Myosin filaments connect cell organelles to actin filaments.

Cytokinesis in a plant cell is accomplished by the formation of a cell plate in the center of the a dynamin-like protein named Phragmoplastin [2] which was identified in soybean and demonstrated that this protein is associated with the formation of the cell plate during cytokinesis in plant cells. Indirect immunofluorescence microscopy ...
